Comment 0 for bug 1222763

I've got a multimedia wireless keyboard. When I try to type:

/lib/udev/findkeyboards

I get:

USB keyboard: input/event4
AT keyboard: input/event3

Then, if I type:

sudo /lib/udev/keymap -i input/event4

pressing the multimedia keys print nothing in the command output
(while the standard keys print output as expected. Example:
scan code: 0x70018 key code: u).

I'm using the 3.2.0-41-generic kernel with Lubuntu 12.04, but this problem is present also in other kernel versions.

The udevadm info --export-db (with connected and not connected keyboard) output and the diff command output are attached to this bug report.
