/dev/input/mouse0 and /dev/input/mouse1 generate events when I move
internal/USB mouse.

ls -al /dev/input/mouse0 
crw-rw---- 1 root root 13, 32 Apr 25  2010 /dev/input/mouse0
pavel@amd:/tmp$ ls -al /dev/input/mouse1
crw------T 1 root root 13, 33 Aug 30 16:41 /dev/input/mouse1
pavel@amd:/tmp$

/dev/hidraw0 seems to correspond to USB mouse and generates
events. Could not find hidraw corresponding to PS/2 mouse.

So it seems to be "/dev/input/mice" issue. Does it work for you?

Thanks,
