All of a sudden, this Dell Optiplex with Win 8.1 64-bit, doesn't like the external USB drive that's connected to it. No hardware or software changes involved--it just threw a "device not recognized" message (per the user).
When I check it in Device Manager, the obligatory yellow warning icon is next to it with "unknown USB device (port reset failed)."
Currently, it is similarly unhappy with all four Win 8.1 machines, but will cooperate with a lowly WinXP machine.
Uninstalling the device, rebooting the PC, then connecting to the same or different USB ports yields no joy.
Anybody have a tip or clue to shove me in the right direction?
