On my dads custom made pc, he has Windows 7 home 64bit. Just recently, the error message "USB device has stopped working" constantly keeps appearing and disappearing. When I mean constantly, I mean like every few mins, sometimes it increases to every few seconds.
If I take a look in Device Manager, you will see an Unknown Device appearing and disappearing from the list of USB devices.
I plugged out all the USB devices out of the computer and the error still pops up.
Google search suggests reloading the USB drivers. So I uninstalled everything listed under USB devices, like the USB hubs and such. It gave me the option of deleting the drivers and I chose no, (only reinstalling them right?) and then restarted the computer.
The computer installed the drivers for them again, all except an unknown device, that has stopped working. And the error appears and reappears again and again.
Only thing USB device plugged in when it restarted was the mouse. The keyboard is PS/2.
Anyone has suggestions on what next I could try?
