Comment 3 for bug 321740

You want this to be done before or after replugging the Cordless Receiver ?
I'll do it before replugging - as that's where it doesn't work. also - I use kubuntu - anything I should killt here before doing it ?
gnome-settings-daemon is not used here.

With xev - all Multimedia keys, _ALL_ are not working. This includes:
Go, Back, User, F-Lock, E-Mail, Messenger-MSN, Webcam, Previous/Next Track, Media Key, Volume Up/Down, PLay/Pause, Stop, iTouch, Search, Shopping, Favorites and MyHome.

On the Mouse - Buttons 4, 5, 6 are not working.

So - it's a total loss of any non keyboard specific functionality. IMHO the driver goes into fallback defaults mode.
