i use my gh controller in linux.
build 192 of FOF required a key mapper
i used this one for linux as its very easy
its called Qjoypad
with the new 225 build... i no longer require Qjoypad in linux to use my strum bar.
also .. i use the radio shack usb converter with is automatically detected and setup with zero configuration just like in windows.
in fact i find that FoF plays better in nix than windows!
those using windows and looking for a very user friendly distro check out [url=http://www.freespire.org]Freespire
