ir-keytable will not see it by default, because it doesn't exist in
/sys/class/rc/. Mine created devices at /dev/input/event5 (keyboard) and
/dev/input/event6 (mouse) by default. The udev rules I posted on the wiki
add a symlink at /dev/input/irremote0 (keyboard) and /dev/input/irremote1
(mouse). You could try to find it using `ir-keytable -d /dev/input/event0`
and increment the number after event until you find it. My receiver says
this for that command:
Name: HID 05a4:9881
bus: 3, vendor/product: 05a4:9881, version: 0x0110
Then you can show the scancode-key map by `ir-keytable -r -d
/dev/input/event4` or whatever event# you find it at.
