I'm not sure, my copy has always done something similar--and I've had this with XP pro/corp and MCE--except it's just the mouse. Not sure if it's software (Windows) or the hardware (the motherboard's USB plugs)...I'd guess the latter except Debian has never had a problem.
Nonetheless, the easiest solution (which I guess isn't too plausible in your situation being so frequent--but temporary anyway): just unplug the USB cable and plug it back in.
