Bug#282035: xserver-xfree86: [kbd] Logitech "Internet Navigator Special Edition" / "Elite" USB Keyboard missing 4 buttons

[Stephane Chauveau <stephane@chauveau-central.net>]

I have a simular keyboard and I investigated the problem a few months ago.
This is a kernel problem.

You can see it by pressing the keys from the console.
You should get the following errors:

Dec 19 21:06:16 localhost kernel: atkbd.c: Unknown key pressed 
(translated set 2, code 0x91 on isa0060/serio0).
Dec 19 21:06:16 localhost kernel: atkbd.c: Use 'setkeycodes e011 
<keycode>' to make it known.

Those messages should also appear in the kernel logs.

I explained the problem and gave a 'hack' to solve it in the following 
link some months ago:

I hope that helps.
