What is the cause of the error “Unknown USB Device (failed to reset port)” in Windows 10?

There are several causes of the problem that can help you determine the right method to use to solve the problem. For this reason we strongly recommend you to read the list below!

  • Old or defective drivers. Old or incorrectly installed drivers can prevent your computer from recognizing an installed device. Consider reinstalling or updating!
  • The device is turned off. Sometimes your computer turns off certain devices to save power, which may cause this problem. Be sure to turn this option off in Device Manager.

Error may be caused by hardware problems. So first of all, just follow the simple instructions below to fix the problem.

Try the USB Device with a Different USB Port

In some cases the device request descriptor may not work because the USB port does not work properly. In this case you need to check each available USB port individually. This way you can see if the problem is related to the port.

Connect a USB device to one port at a time. Repeat the process until you have tried all the USB ports. It is not difficult to determine which port has failed.

Update the USB Power Management Setting

Power management is also considered to be the cause of problems with USB. Uncheck this box to solve the problem.

  • First open Device Manager (enter “Device Manager” in the Start menu). Now scroll down and expand the Universal Serial Bus Controller branch.
  • Double-click the USB root hub device and click the Power Management tab. Here, uncheck “Allow my computer to shut down” to save power and click “OK”. After restarting Windows, check if this trick works for you.

Update your USB Driver

Change the USB Selective Suspend Settings
