xev does not recognize my keys

[trumee]

Hi all,
I have a Logitech Access keyboard, model Y-SR34. There a couple of extra multimedia keys provided which i am trying to configure.
Unfortunately, only some of the keys are getting recognised but there are two keys which do not give any scan code in xev.

The keys are for "Messenger/SMS" and "Webcam", is there any way i can get these working in xev. I have already tried lineakd and khotkeys but if there are no scancodes present, these apps cannot do anything.

My input section in XF86Config looks like this

-----------------------------------------------------------------
Section "InputDevice"

Identifier "Keyboard1"
Driver "Keyboard"

Option "XkbRules" "xfree86"
Option "XkbModel" "logicdn"
Option "XkbLayout" "gb"

EndSection
-----------------------------------------------------------------

any ideas?

Thanks

You sure you got the right keyboard model in xkbmodel? According to what you have there, the keyboard should be "Logitech Cordless Desktop Navigator"

Here, from /etc/X11/xkb/rules/xfree86.lst:

Actually, my model does not even exist in the list. I checked the photographs of the keyboards in lineakconfig and logicdn is the closest i have found. It has the SMS key in it.
Btw, is it possible to define a new keyboard on my own?

Thanks
