I never did get all of this to work with a MOMO Racing (black) wheel. The wheel by itself was ok, however i had combined not separate axis for the pedals and no FF. I'd like do some further investigation on the why, I only really started to look into it, when rFactor and GTR2 started to work in wine. I think this wheel is acting similar to the G25, starting in a compatibility mode, and needed commands to set it to native. I'm not sure if the hardware itself is a single axis for the pedals, with some separation done in the driver to report two separate ones. I've seen a patch for a 2.4 kernel to this effect. If there's some serious work going into better support of the Logitech loops, I'd like to keep in the loop and contribute. Jean-Philippe probably has the best overall explanation of it all, as when I was looking for information, it was sparse at best and conflicting at worst. Is there someone at Logitech that could offer up some actual documentation? 2008/5/12 Annick et Jean-Philippe <jpmeuret@xxxxxxx>: > Hi, all. > > For the happy owners of a Logitech G25 wheel that did not manage yet > to enjoy the full features of the beast under Linux, this is a small > summary of what I found on the net and my own humble experience about it > on a 2.6.22.9 Kernel (Mandriva 2008.0 x86_64) : > > Note: This is only my own understanding and summarizing of what people cleverer > than me discovered by themselves.
