Could you please provide output of

	cat /sys/kernel/debug/hid/<device>/rdesc

and

	cat /sys/kernel/debug/hid/<device>/events

(the second command should be run when the non-working button is presse=
d=20
on the device).

This works on kernels 2.6.32 an newer -- for older ones you'll have to=20
recompile your kernel with CONFIG_HID_DEBUG, modprobe the hid module wi=
th=20
'debug=3D2' parameter, and look into dmesg output.
