Hello.

I have Genius Ergomedia 700 USB keyboard but not all "multimedia" keys 
are working.
In manual it's written that "My document/My picture/My music/Scrolling 
buttons/Left and right scrolling functions/Zoom in/Zoom 
out/Messenger/Messenger status/Webcam/Audio 1-3/Word/Excel/Powerpoint do 
not function unless driver has been installed". And exactly those keys 
do not working while other multimedia keys are working fine.

What can be done to enable those additional multimedia keys?

When plugging it in it appears as 2 input devices:
input: KYE 4D device Ergomedia as /class/input/input1
input: USB HID v1.10 Keyboard [KYE 4D device Ergomedia] on 
usb-0000:00:1d.1-1
input: KYE 4D device Ergomedia as /class/input/input2
input: USB HID v1.10 Device [KYE 4D device Ergomedia] on usb-0000:00:1d.1-1

lsusb -v output in attachment.

Alex.
