Easiest way to do this is: 1: type cat /proc/interrupts and see the number of interrupts in each line. 2: move the mouse. 3: check the number of interrupts again. Each mouse movement will reliably increment some interrupt's count.. (couple of them may increase , for e.g timer..) But you can easily narrow it down. Btw, I see the interrupt numbers are in the hundreds..
