There are apparently are some semi-experimental FFB drivers out there for a few wheels... but yeah, most hardware has a zero percent chance of working, because it's a niche of a niche. And then if you're doing online racing, they all(?) have anti-cheat stuff that won't work for you anyway.

If games transition to SteamOS/Linux in general, I think this niche is going to be one of the slower ones to move, but never say never.
