I'm confident this is a hardware problem. The USB plug is detected by one of
the analog inputs the CPU provides, the keys are done by two other analog
channels. Somehow your box seems to have crosstalk between those. Not much I
can advise for, except to open it up and check for bad soldering or shorts.
Maybe some humidity went in?
