I found your ultimate-g15-toys package and installed it, on the off chance it might support a Logitech G13... but alas, either I did something wrong or it could care less about a Logitech G13. That said, is there some support for G13 elsewhere either in Ultimate Edition Gamers, Ultimate Edition 2.8, or perhaps even outside Ultimate Edition entirely?
I've done some google searches, but only to find outdated vaporware projects.
