I haven't had a PS/2 mouse in a long time, but I thought I remember that if you unplugged a PS/2 mouse and then replugged it back into the PS/2 port while the computer was on, that the mouse would no longer respond.
I'm curious if this is true or not because someone I know is telling me they're having issues with their PS/2 mouse and I think they may be plugging it in/out while the computer is running. They're running Windows XP.
Also, if the mouse no longer responds, why is this? Why does't a USB mouse NOT have this problem?
