Writing a driver for Logitech G710+, need help.

[K900]

Hi,
I've got a Logitech G710+ keyboard here, and it's not exactly 100%
working ('normal' keys and media controls work, 'programmable' keys
don't) out of the box. So I started playing with it, and I think I
know how to implement all the features (spec wise). I have Python
proof-of-concept code here: https://github.com/K900/g710 , but I don't
really know how to implement that in the kernel. Can someone please
help me? Sorry for my exceptional noob-ness.

Thanks in advance,
Ilya
