Windows 10: None of my USB devices are connecting to my computer. How do I solve this?

Usually, when I have computer problems they go away after restarting/shutting down. But, my mouse hasn't been working and I thought it was the battery but that wasn't it since it works on another computer. I also use an art tablet that's connected through USB which hasn't been working. I have no idea why my USB's aren't working, I've tried restarting and other things from what I've searched through google but so far it's been a total waste of time. Can anyone help me with this problem? Anything helps, thanks.

I cannot see how much power USB devices draw

Hi Suat,

Welcome to Microsoft Community.

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

• Power: If the USB device operates on battery power,
  make sure all the power connections are secure and the power cord is connected to a power source.
• Test the USB connection: Sometimes, simply disconnecting and reconnecting the USB device to the computer can solve the problem:

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

Let us know the status.

unknown device USB

Hi Ali,

In most cases, this issue can be caused by either an unstable/ corrupt USB controller or your computer's drivers need to be updated.

For us to isolate the possibilities, we suggest that you perform the following troubleshooting steps in succeeding order:

• Connect your USB drive to a different port. Alternatively, try to connect it to a different PC.
• Connect a different USB drive to your PC.
• Unplug your USB drive and restart your system. Afterwards, plug it in and see if it works. If the same issue occurs, perform a complete shutdown and wait for a few minutes before turning it on again.
  
• Update your drivers.

If you find that the USB drive still doesn't work even after performing all these suggestions, this is most likely pointing to a hardware issue. Thus, it would be best to get in touch with your device manufacturer for a thorough check of the device.

If you have any other questions or concerns, feel free to post back and let us know.
