Logitech G930 & Huion 610 driver issues

So I have a Logitech G930 headset, and a Huion 610 pro graphics tablet, and they are functional, but I have a few bugs.

My G930 headset has 3 programmable “g buttons” that you can bind to anything you want. It also has a volume scrolly rocker wheel thing to adjust the volume. The volume scrolly wheel rocker thingy is mainly what I want to get working, and also the 7.1/5.1 surround sound.

I assume to fix the volume control would just be a matter of binding it to some type of script or something?

My graphics tablet is picked up, and I notice there is support for Wacom tablets in the settings. Problem is Ubuntu doesn’t pick up my graphics tablet’s buttons or pressure sensitivity. Is there like a hack I can do to make it work like a Wacom?

Thanks

Regarding the Huion 610 pro graphics tablet, there is a “DIGImend kernel driver” in the Digimend project.
Its status is “works” and installation is pretty simple, just download it from here then do “make” and “sudo make install” in the directory where the the sources are stored.
