keymap rule which fixes the micmute button

The micmute button on the Plantronics .Audio 626 DSP headset is recognized as
some kind of keyboard modifier and messes up xorg input when it's turned ON.

This is all I needed to add to /lib/udev/rules.d/95-keymap.rules on Debian
(udev 204-8) to fix it:

    ENV{ID_VENDOR_ID}=="047f", ENV{ID_MODEL_ID}=="c006", RUN+="keymap $name
0xb002f micmute"</pre>
