Well, this worked for me.

The guy indicated that the device box was "completely blank", so I checked and it was, which is... odd. Idk why, but this problem started today for me, after cleaning my PC. It might have something to do with hardware detection (connecting headsets after a complete system restart, full power unplug and all)
Hope this help to someone.
