I have just managed to get the digimend kernel drivers packaged for guix:
https://framagit.org/marlin1113/guix-digimend-drivers
This allowed me to work with my huion graphics tablet using the guix system. It's my first trial at packaging too, so i'll have to get some better documentation on the repo.
Consider merging this package
