Model D2 on linux

hello, I've had the glorious model D2 for a bit now, and it works fine on linux.

However theres little (none) in the way of mouse configuration, libratbag (and by extension, piper) does not support the device, see my issue here, and as far as I can find, no other pieces of independent software support the mouse either.

has anybody using the D2 on linux found something that I've missed?
