5 Advanced Fixes to Unknown USB Device (Device Descriptor Request Failed) in Windows 10

Due to the uncertainty of the exact factor that causes your USB drive malfunctioning in this way, the demonstrated solutions are not all supposed to take effect. Hence, take some patience to implement each solution until the problem solved.

1. Use Hardware and Devices troubleshooter

  • Press Win+R, type Control Panel and hit Enter.
  • Inside Control Panel in the search box type troubleshooter and select Troubleshooting.
  • After that select Configure a device under Hardware and Sound and follow the on-screen instruction.
  • Click on Apply this fix if any problem is found.

If the unknown USB device error is triggered by hardware issues, it will no longer appear after you try the above steps. If not, you need to move on to the next method to find a fix.

2. Try to Uninstall USB Drivers

  • Open Device Manager (Right Click on Windows Logo and Click Device Manager).
  • Now find and expand Universal Serial Bus controllers. Now right-click on USB drivers and click Uninstall. Do for all USB drivers one by one.
  • Restart your PC then Windows will reinstall the device automatically.

Some people would find that uninstalling and reinstalling the driver only works once. The next time they plug in the drive, and the device descriptor request failed appears again. According to an experienced user who has been suffering the problem for long but finally found the cause of why this method does not work and how to make it work.

I found that going into Device Manager and 'Uninstalling the device', and then plugging in the USB I had been using at the time, before telling Device Manager to scan for hardware changes in the USB ports fixed this problem. I think it was because I've had this USB receiver for a mouse plugged into it for so long, that when I removed it from the port, the computer didn't recognize that it'd been removed and got caught in a loop trying to identify a device that wasn't there anymore, locking the USB port down. Works fine now.

3. Disable Fast Startup
