More than 256 scankey on a Logitech keyboard

[<fr...@fr...>]

Hi,
    I've a USB logitech keyboard with a lot more key than the standard AT 
keyboard. So, 4 keys have a scancode > than 255. And the driver reply that it 
can't map  such keycode. The other keys work, but thoose with a scancode > 255 
don't.

    Is there a patch to allow all my keys to work?

    There's also a tiny wheel on the keyboard with a button which act like a 
keyboard key (it returns a scancode). How can I make it work with X?

   I've also a 5 button PS/2 mouse that I like to use with X the 2 extra 
button have no effect.... But I think that for this latter question, I should 
ask somewhere else.

Thanks,
Freeze
