hi dave,
this is a complete shot in the dark, but maybe it helps. some time ago i
configured my usb-mouse to have all extra-buttons working and found some
how-to's that deal with 'evdev'. 
so the point is to set things like that: (my mouse for example)

    Driver "mouse"
    Option "Protocol"   "evdev"
    Option "Dev Phys" "usb-0000:00:02.1-1/input0"
    Option "Dev Name" "B16_b_02 USB-PS/2 Optical Mouse"
    Option "Device"     "/dev/input/mice"

to find out which devices are there you
'cat /proc/bus/input/devices'

and to find out what events get triggered when moving and clicking the
device you run 'xev'. this opens a litte window where you move and click
the device and the terminal shows some useful output.

maybe its worth to look at this direction...
