Support for Gigabyte AORUS 17G KD

[pohlymorph]

Hi and a good day, @blmhemu.
I stumbled upon your repository and the AUR package provided by @rcassani -- and in my grief to have bought a laptop that has so limited/none Linux support (by its vendor) I had high hopes...

• I managed to add a new usb product id 7A3D -- I have a 'hardware probe' here
• I can 'insmod ... gigabytekbd' and as per 'lsmod' the driver module is loaded
• now I can press Fn-F3/Fn-F4 and the Xcfe Power Manager picks up the events and I can finally control the brightness with decency 🥰

Thanks to all of you who made this publicly available 🙇‍♂️

May I ask some questions:

• Is the 'insmod ... gigabytekbd' the intended way of loading the module? Or should it get loaded automagically? (see next question)

• I had the feeling that the provided/modified udev rule was supposed to insert the driver module - can you shortly elaborate under which condition this rule should do what?

Kind regards

P.S. Would you consider to accept a pull-request?
