Description Marc Dahlhaus 2005-03-28 15:22:14 UTC 
My keyboard [ Logitech Cordless Desktop Optical ( Y-RJ20 ) ] generates keycodes
 from 256 to 259, 261 and from 336 to 347 for media keys as long as it's
attached to usb, over PS/2 all generated Keycodes are < 256.

i don't want to use my keyboard over PS/2 because it's battery powered cordless
version and i read the battery status over libusb ( KDE does it also this way )
and there is no way to get this under PS/2.

[ as far as i know there are may other keyboards that use keycodes higher than
255 for media keys ( some Dell Notebooks does this ) ]

I want to use my mediakeys under Xorg please add support for keycodes > 255

This is not XKB configuration database problem, so I am redirecting this bug...

this is because of the way the Linux console keyboard stuff works.  evdev
supports higher keycodes, and is the generally-blessed Way Of The Future.
