When you issue "lsmod" do you have "usbhid"?
And in xorg.conf I've got:
Code:
Identifier "Mouse1"
Driver "mouse"
Option "Protocol" "IMPS/2"
Option "ZAxisMapping" "4 5"
# The mouse device. The device is normally set to /dev/mouse,
Option "Device" "/dev/mouse"
# Option "Device" "/dev/psaux"
on this box with a Logitech wireless mouse/kbd combo.
