Vok, I already messaged you, but since there's only 2 days left for our game: I'm available most of today and tomorrow evening, so lemme know what time's good for you.
The Linux driver is available here: https://bitbucket.org/Swoogan/aziokbd (you should be able to install it without using another keyboard, the only keys not working without that driver are the Ctrl, Alt, Menu and Windows keys).
The 200K doesn't work with Linux without a special driver and also doesn't work in many UEFI/BIOS at all because it uses a non-standard USB protocol. It also doesn't work with OS X.
