Added udev rule for the headset.

There's an issue with the idProduct/idVendor detection that prevent
for now both the research and the consumer headset to be distinguished...

Can be solved if someone send me the output of:
udevadm info --name=/dev/hidraw2 --attribute-walk for the consumer
headset.
