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.
