Chances are, you're using /dev/input/mice, which blends all USB mouse 
input into one logical device (partially so that mouse input in the X 
server continues to work as you plug and unplug mice).

I don't know if there's a better solution for this under X11 at the 
moment. Someone else might know, though.
