I think page 61 is just an example of one possible report descriptor
for a mouse. Could you follow the instructions below to get the
report descriptor for your mouse and post it to the list?

 o Remove the `ums' device from your kernel config, but leave in
   the `uhid' device (if you're using modules, just unload ums and
   make sure uhid is loaded).

 o Plug in the mouse

 o Check dmesg for the correct uhid device, e.g. you should see
   something like:

	uhid0: Logitech USB Mouse, rev 1.10/4.10, addr 2, iclass 3/1

 o Run this command

	usbhidctl -f /dev/uhid0 -ra

   replacing the uhid0 name with the correct device for your mouse.
