[Launchpad Bug Tracker]

You have been subscribed to a public bug:

Binary package hint: udev

Hotkeys of multimedia buttons get assigned same scan code 0x00 in sudo /lib/udev/keymap -i input/event8
Like this:
> ~$ sudo /lib/udev/keymap -i input/event8
Press ESC to finish
scan code: 0x00   key code: screenlock
scan code: 0x00   key code: 14A
scan code: 0x00   key code: prog1
scan code: 0x00   key code: email
scan code: 0x00   key code: www
scan code: 0x00   key code: nextsong
scan code: 0x00   key code: previoussong
scan code: 0x00   key code: playpause
scan code: 0x00   key code: stopcd


Though the key codes differ are mostly correct (except for screenlock, which is run key (fn+space) and 14A which is for touchpad turn on/off) and I am not sure about prog1)

the keydump consists of single line:
> ~$ sudo /lib/udev/keymap input/event8
### evdev 1.0.0., driver 'Asus Laptop extra buttons'

acpi_listen detects the keys as:

> ~$ acpi_listen
hotkey ATKD 0000005c 00000046
hotkey ATKD 0000006b 00000021
hotkey ATKD 0000008a 0000000d
hotkey ATKD 00000050 00000004
hotkey ATKD 00000051 00000004
hotkey ATKD 00000041 0000001c
hotkey ATKD 00000040 00000008
hotkey ATKD 00000045 00000006
hotkey ATKD 00000043 00000004

This does not allow to change the key bindings as all scan codes are the same.
Expected behaviour: different scan codes
