I installed evemu.

I see the following in /dev/input:

It seems like there are multiple input chardevs for both the keyboard and
mouse:

jharvell at wolfhound /dev/input $ sudo evemu-describe mouse
mouse0  mouse1  
jharvell at wolfhound /dev/input $ sudo evemu-describe mouse0 
error: could not describe device
jharvell at wolfhound /dev/input $ sudo evemu-describe mouse1
error: could not describe device

I am guessing the problem is the two evdevs for the same mouse.  If you want me
to do an evemu-record to confirm, I gues you want me to do that on both event11
and event12?
