It would be interesting to attach a UART to the comm link (4800 bps, RS-232
signal levels) and capture what happens. It's quite strange to see a system
failure caused by pressing a button. I suppose it could be a bug in the system
software mishandling a protocol error on the mouse to system link. Or perhaps
the mouse embedded controller has failed so that pressing the button in
question crashes the controller and makes it stop talking to the host. In that
case you'd think that unplugging and replugging the mouse would cure the issue,
though.
