Actions

This document describes common errors and general troubleshooting tips for Universal Serial Bus (USB) devices, such as hubs, thumb drives, printers, and cameras.

Depending on your version of Windows, some graphics and information in this document might vary slightly.

Before you troubleshoot a USB connection

Some USB devices, such as printers, scanners, and copiers require that the USB device software and drivers be installed before connecting the USB device to the computer. Always follow the installation documentation from the USB device manufacturer.

While troubleshooting the USB device, you might need to disconnect the USB device from the computer.

CAUTION:

Always follow manufacturer instructions for disconnecting USB devices from the computer. Some USB devices must be turned off and/or ejected before they are disconnected from the computer. Some other USB devices support the Windows Safely Remove Hardware feature.

Steps to troubleshoot a USB connection

Perform the following steps, as applicable, to troubleshoot USB devices that are not working correctly.

  1. Power: If the USB device operates on battery power, make sure the batteries are correctly seated and are functional. If the USB device operates on external power, make sure that all the power connections are secure and the power cord is connected to a power source.

  2. Test the USB connection: Sometimes, simply disconnecting and reconnecting the USB device to the computer can solve the problem:

    1. Disconnect all USB devices from the computer except a USB mouse and keyboard (if in use). This includes hubs, thumb drives, printers, and cameras.

    2. With all USB devices disconnected, do one of the following:

      • If you have a desktop computer, connect the device that is not working correctly to one of the USB ports on the back of the computer (the ports attached directly to the motherboard).

      • If you have a notebook computer, connect the device that is not working correctly to a USB port on the notebook. Do not use a USB port replicator (such as a docking station or USB hub).

    What happens when the device is connected?

    • The device works correctly: The problem is most likely related to power or poor overall system performance.

      Note:

      To prevent the USB device from failing in the future: Do not connect too many devices to the computer; wait 5 seconds after connecting a device before using it; use powered hubs to connect other devices; and do not attach USB devices when the system is busy (running slower than normal).

    • The device does not work: Leave the device connected and continue to the next step.

  3. Install the USB device manufacturer software. Some USB devices require manufacturer software be installed before the USB device will work.

    1. If the USB device came with software, and it was not previously installed, install the software now, following the manufacturer instructions.

    2. After installing manufacturer software, reconnect the USB device that was having problems.

    The device should now work correctly. If problems persist, continue to the next step.

  4. Try a Microsoft easy-fix solution. Microsoft provides a web-based automatic diagnostic and repair application. Go to the How to use Microsoft easy fix solutions webpage (in English) and select the troubleshooter that most closely matches your issue. Then follow the on-screen instructions. If the device still does not work, go to the next step.

  5. Run Windows Update to check for operating system updates required for your computer. Go to Windows Update (in English) and follow the on-screen steps to check for updates, and opt in on all recommended and optional driver updates. If the device still does not work, go to the next step.

  6. If the USB device was previously working, then subsequently became unusable, try Microsoft System Restore to go back to a time prior to when the device failed. See HP PCs - Using Microsoft System Restore (Windows 10, 8) for more information. If the device still does not work, go to the next step.

If the device still does not display in the Safely Remove Hardware window, then restart the computer, and repeat this process.

Memory card is not shown in Safely Remove Hardware window

If the device is not shown in the Safely Remove Hardware window is a memory card in a USB card reader, restarting the computer should correct the problem. Do not use the Safely Remove Hardware icon to remove a memory card. To remove a memory card, use Windows to eject the card by following these steps.

Safely Remove Hardware window
  1. When the light on the reader is not flashing, insert a memory card.

    An Autoplay window displays. If it does not display, open the card using Window Explorer.

  2. The memory card has a drive letter associated with it, just like a floppy drive, CD-ROM drive, or hard drive. Use the memory card as you would use any other drive on the computer. For example, double-click the memory card icon to open a new window showing the files on the CompactFlash card.

  3. When you have finished working with the files on a memory card, right-click the memory card icon and select Eject.

    Eject Removable Disk selection
  4. Wait for the light on the memory card reader to turn off or stop flashing.

  5. Remove the memory card from its slot.

Front USB ports do not work on a desktop computer

If your desktop computer came with USB ports on the front of the computer and they do not work, a cable inside the computer might have become disconnected.

First, make sure the USB ports at the rear of the computer work by connecting a USB device to the rear port. If the device is not recognized in the rear port, see Steps to troubleshoot a USB connection. Use the following steps to see if the front USB ports have become disconnected from the system board.

CAUTION:

This product contains components that can be damaged by electrostatic discharge (ESD). To reduce the chance of ESD damage, work over a non-carpeted floor, use a static dissipative work surface (such as a conductive foam pad), and wear an ESD wrist strap connected to a grounded surface.

  1. Turn off the computer, disconnect the power cable, and position the computer so that you can easily work on it. If necessary, disconnect cables and move the computer to a table over a non-carpeted floor.

  2. Remove the side panel. If needed, you can find instructions that specifically match your computer by searching HP Customer Support (at the top of this page) using the model number of your computer and the term "".

  3. Look inside the computer. Wires coming from the USB PCA board at the front of the computer are routed to a set of USB pins on the system board. Make sure that this connection is secure. If the wires are not connected or are partially connected, secure the wires to the proper USB connection on the system board.

    To find where the USB connector is located on the system board, look for 5 pairs of pins with a label that starts with USB, JUSB, FRONT_USB, or F_USB. If your system board has two sets of pins, FUSB1 and USB2 for example, use the lower number first. Also, you can refer to the system board specification that matches your specific model of computer. Find the system board specification from the HP Customer Support for your computer model.

    Image of USB connection on system board
  4. After the front USB wires are connected securely, replace the side panel.

  5. Make sure that there are no devices or cables connected to the front USB ports.

  6. Connect the power cable (and the mouse and keyboard if they were previously disconnected).

  7. Turn on the computer and wait for Windows to find the new hardware.

  8. You can use the front ports after Windows has installed drivers for the USB ports.

The mouse responds slowly, if at all

If your computer does not recognize the mouse or if the mouse is very slow to respond, download and install the latest USB driver.

Note:

Not every computer or mouse needs this update.

  1. Go to the HP Drivers & Support webpage.

  2. Use one of the available methods to identify your computer model. The software and driver results page displays when the computer model is identified.

  3. Click Driver – Chipset.

  4. Download the USB Driver, and then follow the on-screen instructions to complete the installation.

  5. After the driver has downloaded and installed, restart the computer.

USB device does not work in USB port

Some USB devices do not work in USB ports. To fix this, uninstall the USB driver in Device Manager.

  1. In Windows, search for and open Device Manager.

  2. Double-click Universal Serial Bus Controllers to expand the list, and then locate the USB root hubs.

    Locating the USB Root Hub
  3. Right-click the USB Root Hub, and then click Uninstall.

Are you getting a “USB device not recognized” error whenever you plug in a USB mouse, keyboard, camera, or other device? I can&#;t live without USB ports and currently have 5 ports on my computer so that I can connect my mouse, keyboard, camera, phone, and printer to it all at once!

For those of you with even more USB gadgets, you probably have connected a USB hub to one of your USB ports so that can you connect even more devices. Most of the time this works great, but occasionally your computer might stop recognizing USB devices. The odd thing about this error is that the ports are working just fine, as I was able to still charge my cell phone without a problem, but couldn&#;t get my camera recognized using the same port.

usb device not recognized

After spending a lot of time and trying a bunch of different ways to fix the problem, only one solution ended up working for me. I&#;ll mention that solution first, but will also mention the other possible solutions, as the first solution may not fix the problem for everyone.

USB DRIVE NOT SHOWING UP: In Windows

Also, check out our YouTube video if your USB drive is not showing up on your Windows computer.

Method 1 &#; Unplug Computer

So how did I finally fix the problem? Well, if you are lucky, it’s a super simple solution! Try this method first and if it works, you&#;ll have saved a lot of time.

Simply unplug your computer from the power supply. Yes that is it! Note that this does not mean just turning off your computer using the power button because most modern computers don&#;t actually turn off completely and the motherboard will still get power. This is useful sometimes if you want to remotely wake up a computer, etc.

 The motherboard is where all of hardware of the computer connects to, including the USB ports. Sometimes the motherboard needs to be “rebooted” because things can go wrong, i.e. all or some USB ports suddenly stop working. The small microprocessor on the motherboard will reload the drivers and your USB ports should hopefully be recognizing devices again.

So first turn off your computer using the Shut Down option in Windows or pressing the power button and then UNPLUG the PC from the wall outlet. Let it sit for several minutes and then plug it back in.

Method 2 &#; Update Device Driver

If Windows is not able to recognize the device, you may also see in Device Manager that the device shows up as an “Unknown Device”. You can get to Device Manager by clicking on Start and typing in devmgmt.msc or by going to Control Panel and clicking on Device Manager.

unknown usb device

In that case, you should right-click on Unknown Device, click on Properties, then the Driver tab and then click Update Driver.

update driver

If this doesn&#;t work, you can also try to download the driver for your device from the manufacturer&#;s website. If the USB device is just a flash drive, then it&#;s probably not a driver issue. However, if you are installing a USB printer, drawing pad, etc, then it might be worth downloading the driver for that specific device.

Method 3 &#; Restart & Disconnect USB Devices

The next thing you can try is to disconnect all USB devices and then restart the machine. once you have restarted, try to connect the USB device that was causing the problem.

If that particular USB port doesn&#;t recognize it, try another one. If the device is recognized by a different USB port, there could be a hardware problem with one of the USB ports. If no USB port recognizes the device, then keep reading because it&#;s probably something else.

Method 4 &#; USB Root Hub

Another thing you can try is to open Device Manager, expand USB Serial Bus Controllers, right-click on USB Root Hub and then click on Properties.

usb root hub

Click on the Power Management tab and uncheck the Allow the computer to turn off this device to save power box. If you have more than one USB Root Hub listed, you need to repeat these steps for each one.

usb root hub prop

Click OK and then restart your computer. Try to reconnect the USB device and see if it is recognized. If not, go back to the power management tab for each one and check the box again. If it does recognize the device, then leave them unchecked.

Method 5 &#; Connect Directly to PC

A friend of mine ran into this issue and the cause ended up being his USB hub. He only had three USB ports on his computer, so he bought a hub where he could connect an additional 8 USB devices.

I guess this proved too much for his computer and it just started sporadically not recognizing various devices. After removing the hub and connecting the device directly to the computer, it worked just fine.

We haven&#;t really been able to find any other solution to this problem other than reducing the number of items connected to the hub. Actually, one other solution worked, but it meant having to buy a new USB hub with more power.

If you are having this problem with Windows 8 or Windows , then you might be in luck. Microsoft has released a fix for Windows 8 not detecting USB devices properly. Make sure to install this hotfix if running Windows 8.

Method 6 &#; USB Troubleshooter

If nothing has worked so far, you can download the Windows USB Troubleshooter Fixit tool. It&#;s a free tool that works with Windows XP, Vista and 7.

windows usb troubleshooter

You can either have the troubleshooter fix the problems for you or select the fixes yourself. I would just let it fix them for you since the choices can sometimes be confusing and technical for the novice user.

Method 7 &#; Update Generic USB Hub

If you are getting the Unknown Device error in Device Manager, you can also try one other thing. Open Device Manager and then expand Universal Serial Bus Controllers.

You should see at least one item called Generic USB Hub. On some computers, you might see two, three or more of these. Right-click on the first one and choose Update Driver Software.

update generic usb hub

When the update dialog pops up, choose Browse my computer for driver software.

pick driver

Then click on Let me pick from a list of device drivers on my computer at the bottom.

generic usb hub

From the list, select Generic USB Hub. Normally, there won&#;t be anything else listed except for that one choice. Click Next and then click Close once it finishes installing it.

At this point, the Device Manager screen should refresh and either the unknown device will still be there or it may now be recognized. If it&#;s still showing as not recognized, then you repeat the process for each Generic USB Hub listed.

Method 8 &#; Uninstall USB Devices

As a last resort, you can also try uninstalling all USB devices from your system and then restarting. I mention this last because even though Windows is supposed to automatically recognize the USB controllers, hubs and devices automatically, it can sometimes fail and you&#;ll end up with no USB ports working.

I had a computer with 6 USB ports and only one port would not work properly. I uninstalled everything under USB Serial Bus Controllers in Device Manager and restarted. Instead of re-detecting everything, I was left with no USB port working, so be careful when using this method.

Go to Device Manager and start uninstalling each item from under USB Serial Bus Controllers. Before you start with anything that is already working, uninstall the items with exclamation points or that are listed as Unknown Device.

uninstall usb

Method 9 &#; Uninstall Hidden Devices

By default, Device Manager doesn&#;t show all devices that have been installed to the system. It basically only shows the ones that are currently connected. However, if you installed a USB printer earlier and now no longer use it, it will still be installed, but won&#;t show up in Device Manager.

Certain hidden or ghost USB devices can cause conflicts with current USB devices and therefore lead to this error. You can view hidden devices in Device Manager by first opening a command prompt and then typing the following two commands:

hidden devices

set DEVMGR_SHOW_DETAILS=1

set DEVMGR_SHOW_NONPRESENT_DEVICES=1

start devmgmt.msc

Once Device Manager loads, you need to click on View and then click on Show Hidden Devices.

show hidden devices

Now you want to expand Imaging Devices, Universal Serial Bus Controllers and Unknown Devices. If you see anything listed there that is greyed out or that says unknown device, go ahead and right-click on them and choose Uninstall. Hopefully, removing the older devices will allow the newer devices to work properly.

Other Possible Solutions

If nothing has worked until this point, it&#;s pretty safe to say there could be a problem with the actual hardware. The best thing to do is to connect the device to another computer and see if it works or not. If not, then it&#;s definitely an issue with the device.

Possible Solution #1 &#; The other possible solutions are to try a different USB cable, if you have one lying around. If not, just buy a new cheap USB cable from Amazon: A to B, A to Micro B, A to Mini B, or A to A. This is a fairly rare problem, but I have seen it occur a few times over my many years doing technical support.

Possible Solution # 2 &#; Another possible solution is to take the device, connect it to another machine and if it does recognize the device properly, to then eject it properly from that computer before reconnecting it to the original computer. I&#;ve seen this problem occur with several flash drives that were unplugged without ejecting properly. After connecting them to another computer and ejecting them properly from there, they suddenly started to show up on the original computer that was not recognizing them.

Possible Solution #3 &#; A few people have had luck getting rid of this problem by updating the BIOS. I&#;ve already written an article about whether it&#;s a good idea or not to update the BIOS, but in this case, it might be worth a try. You can also go into the BIOS and disable USB, restart the computer and then enable USB again. The only thing you need to make sure is that you have a PS2 port on your computer, otherwise you won&#;t be able to do anything once you disable USB in the BIOS if your keyboard and mouse are connected via USB.

Hopefully, one of the many solutions above will solve your USB problem. If not, post a comment and I&#;ll try to help. Enjoy!

How to Fix USB Device Not Recognized in Windows 10

If a USB device doesn’t work with Mac

  • Check the power, port, and cable connections: Make sure the USB device is turned on and its cables are properly connected. If your computer has more than one USB port , switch the device’s cable to another port. If you still can’t use the device, contact the manufacturer for more information.

    If you can use the device after switching ports, connect another device to the first port. If you can’t use this device, shut down the computer and unplug it from the power outlet. Wait about a minute, then plug it back into the power outlet and start up your computer.

    If you still can’t use a device with the port, your computer may need to be serviced. See Find how to service or repair your Mac.

  • Check for missing software: Make sure you installed the latest software for your device. Visit the manufacturer’s website for any updates.

  • Check the USB hub: If the device is connected to a USB hub, make sure the device and the hub are the same speed. Connect USB SuperSpeed devices to a USB SuperSpeed HUB, USB Hi-Speed devices to a USB Hi-Speed hub, and so on.

  • If the device doesn’t have a power cord and is plugged into another USB device that doesn’t have a power cord: Try plugging the device directly into your computer’s USB port or into a USB device that does have a power cord. You might need to disconnect and reconnect the other device as well, if it has stopped responding.

  • If you have many devices connected to your Mac: Disconnect all USB devices except the device you’re testing, an Apple keyboard, and an Apple mouse. Make sure that the device is connected directly to the computer, and that any hubs or extension cables are disconnected. If you can use the device now, the problem may be with one of the other USB devices or hubs you had connected to your computer. Try reconnecting them, one by one, to your computer. When you find the device causing the problem, review its documentation for further troubleshooting steps.

  • Verify that the device appears in System Information: On your Mac, choose Apple menu  > About This Mac. In the overview that appears, click the System Report button.

    Open System Information for me

    In the window that appears, see if the USB device is listed below Hardware in the list on the left. If the device appears but does not work, review the device’s documentation for further troubleshooting steps.

  • Reopen apps:Quit and reopen any apps that use the device.

  • Restart your Mac: Choose Apple menu > Restart.

    [Fixed] USB Ports Not Working in Windows Quickly &#; Easily!

    If you find one of your USB devices on Windows 10 isn&#;t working, read on. Whether it&#;s a USB mouse, keyboard, pen drive, printer, or some other USB devices altogether, this guide should resolve your problem.

    Note that there are 5 possible solutions here. You may not need to try them all; just start at the top of the list and work your way down.

    1: Check if the device itself is faulty
    2: Check your power supply
    3: Check your power management settings
    4: Check your USB device drivers
    5: Check your USB ports

    Method 1: Check if the device itself is faulty

    If the USB device was working before you upgraded to Windows 10, it&#;s unlikely to be faulty. But coincidences do occur. It&#;s certainly possible that your device just happened to die right at the same time that you upgraded Windows. So it&#;s best to rule that possibility out for sure before spending time on more complex troubleshooting.

    To check if the USB device is faulty, simply unplug it (&#;Eject&#; it if it&#;s a USB storage device) and plug it into another computer. If it works, the device is fine. If it doesn&#;t, then you&#;ve isolated the problem! You just need to buy a replacement.

    Method 2: Check your power supply (laptop only)

    Your laptop&#;s power supply delivers power to your USB ports. If, for some reason, it fails to do this properly, the devices plugged into those USB ports may stop working. Sometimes, this can be fixed quite simply:

    1) Unplug the power supply and charger plug from your laptop

    2) Restart your laptop

    3) Connect your USB device to the laptop again

    4) Plug the power supply back in

    Method 3: Check your power management settings

    In order to save power, by default, Windows switches your USB controllers off when they&#;re not in use, and switches them back on again when they&#;re needed. Unfortunately, sometimes this approach doesn&#;t work as intended, and Windows fails to switch your USB controllers on again.

    To rule this out as the cause of your USB woes, just stop Windows from &#;managing&#; power to your USB controllers and devices:

    1) Open Device Manager (type &#;Device Manager&#; in the Windows search field)

    2) Expand the Universal Serial Bus controllers branch

    3) Double-click the first USB Root Hub device in the list (if you see only one USB Root Hub device, that&#;s fine)


    4) Click the Power Management tab

    5) Un-check the Allow the computer to turn off this device to save power checkbox, and click OK.

    6) Repeat steps for each USB Root Hub device in your list of Universal Serial Bus controllers

    Method 4: Check your USB device drivers

    Your USB ports not working problem is probably being caused by driver issues. The steps above may resolve it, but if they don’t, or you’re not confident playing around with drivers manually, you can do it automatically with Driver Easy.

    Driver Easy will automatically recognize your system and find the correct drivers for it. You don&#;t need to know exactly what system your computer is running, you don&#;t need to risk downloading and installing the wrong driver, and you don&#;t need to worry about making a mistake when installing.

    You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 clicks (and you get full support and a day money back guarantee):

    1) Download and install Driver Easy.

    2) Run Driver Easy and click Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.

    3) Click the Update button next to a flagged USB driver to automatically download and install the correct version of this driver (you can do this with the FREE version).

    Or click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system (this requires the Pro version &#; you&#;ll be prompted to upgrade when you click Update All).

    The Pro version of Driver Easy comes with full technical support.
    If you need assistance, please contact Driver Easy’s support team at [email protected]

    Method 5: Check your USB ports

    If none of the above methods resolve your problem, your USB ports might be damaged. To find out, you can take your PC to a repair store and ask them to check. If your USB ports are damaged, the repairer should be able to replace them fairly inexpensively.

    2. Slow USB charger connected

    If you receive the Slow charger connected notification when experiencing the USB-C not working Windows 10 issue, it may have these causes:

    • Your charger is incompatible with your computer or device
    • The charger doesn’t have enough power to charge your computer or device. A computer or device with USB-C connectors has larger power limits, so if the connector supports USB power delivery, charging will be faster and at greater levels of power
    • The charger is not connected to a charging port on your computer or device
    • The charging cable doesn’t meet the power needs for the charger itself, the computer or device
    • There’s dirt or dust within the USB port on your computer or device that may prevent the charger from the proper insertion
    • The charger is connected to your computer or device from through an external dock, or hub

    In order to fix these problems, use the charger and cable that came with your computer or device so as to speed up charging.

    Another operation to resolve the slow charging for fixing the USB-C issue is to clean the port and connector.

    If dirt or dust is stuck in the USB-C port doesn&#;t allow a proper connection, ask for specialized help to clean your device.

    3. Your PC or phone isn’t charging

    The possible causes for this include:

    • An incompatible charger
    • A charger with fewer power limits so it cannot charge your computer or device
    • The charger isn’t connected to the charging port on your computer or device
    • The charging cable doesn’t meet the power needs for the charger, for your computer, or even for your device
    • Dirt or dust in the USB ports may prevent correct insertion of the charger
    • The charger is connected through an external hub or dock

    In order to resolve these possible causes, you can use the charger and cable that came included with your computer or device.

    Also, ensure you’re connecting the charger to the USB-C port on your computer or device, and use compressed air to clean the ports before inserting the USB-C connector.

    4. Display connection might be limited

    Some of the reasons that the display connection may be limited include the connected device or dongle:

    • Has new features for the USB-C connector that your computer or device does not support
    • Is not connected to the correct port on your computer or device
    • Is connected to your computer or device from an external dock or hub
    • Is competing with many other devices or dongles connected to your computer or device that use USB-C connection
    • Has new features for USB-C connectors that the cable does not support

    Solutions to resolving the above causes are to ensure that your external display and cable connected to your computer (or phone) support DisplayPort or MHL alternate modes.

    Run a System Scan to discover potential errors

    Run a PC Scan with Restoro Repair Tool to find errors causing security problems and slowdowns. After the scan is complete, the repair process will replace damaged files with fresh Windows files and components.

    Also ensure the device or dongle is directly connected to your computer or phone, and connected to the USB-C port on your computer or phone, which supports the correct Alternate Mode.

    You can also try and use a different cable and see if that fixes the USB-C not working Windows 10 issue.

    Note: The USB-C connector has Alternate Modes that allow other non-USB connectors to be used with it. These modes include DisplayPort, HDMI, and MHL as alternate display modes.

    5. Missing updates causing USB device not to work

    1. Tap Start, then swipe over to the All Apps list
    2. Select Settings and select Update & Security
    3. Touch Phone Update and select Check for Updates to check for the latest Windows updates and device drivers.

    Note: The USB device not working notification appearing when your USB-C port is faulty may be caused by the Windows version installed on your device, or an unsupported driver.

    If your device already has the latest updates and drivers, try connecting to a Windows PC and see if the USB-C not working Windows 10 issue goes away.

    6. USB port malfunction

    Here, you’ll get either of two types of notifications:

    • The USB port doesn’t support DisplayPort or Thunderbolt, or MHL.
    • The USB device might have limited functionality when connected to this port.

    The possible causes for this are either the connected device or dongle isn’t connected to the correct USB-C port on your computer or device, or it&#;s connected using an external hub or dock.

    To fix this, ensure the device or dongle is connected directly to your computer or phone, and then connect it to the correct USB-C port that supports the device or dongle’s features.

    If you&#;re looking for an adapter, here&#;s a list with the best USB-C to micro USB adapters on the market.


    7. USB or Thunderbolt device functionality might be limited

    The reasons you get this notification when experiencing the USB-C not working Windows 10 issue are similar to those listed at solution number 4.

    Solutions for the above causes are to ensure your computer or device, as well as the cable, supports similar USB-C features as the connected device, and that the device or dongle is directly connected to your computer.

    Also ensure you connect directly the device or dongle to your computer or phone, and make sure to the USB-C port on your computer or phone, which supports the correct Alternate Mode.

    You can also check if you’re using the right cable, and see if that fixes the USB-C not working Windows 10 issue.

    8. USB device might not be working properly

    If your USB device is not working properly, it could be because your computer or device cannot power the connected device.

    It is probably because it isn’t supported, or the amount of power has temporarily been limited to the device because your PC is running on battery power.

    The issue may appear if the computer or device is providing power to other connected devices so it limits power, or it requires more power than what your computer or device can provide.

    In this case, try using a different computer or device, plug a power adapter to your USB device, plug your computer into an external power source so that it’s not running on battery power.

    Also, disconnect other USB devices you’re not using, from your computer.

    9. These two PCs or mobile devices cannot communicate

    This notification may appear when you cannot connect two Windows computers or devices together with the USB-C connection, or the particular connections are not supported.

    In this case, try connecting your Windows computer to a Windows device instead.
