Hello, and thanks for this great software and mod.
I have got the Logitech g25 working great in Driveclub using the Arduino Leonardo and the CP2102. Really simple and after changing the config to fill out all the buttons, it seems to work a treat. Also had to swap the RX and TX pins.
One thing that intrigued me was I have a Fanatec GT3 RS V2 with Clubsport Pedals (V1 I think). This wheel has a PS3 mode you can put it into for use on the PS3. This mode emulates a G25 and when plugged into windows with PS3 mode on, Logitech profiler sees it as a G25.
So I did the same setup as the g25, used the same config and the Fanatec wheel works great in Driveclub, all the buttons seem to work and the pedals do. I don't have a H-shifter so I am unable to test that, but even better than having the G25 working is having the Fanatec working as I prefer this wheel.
I believe that the Fanatec GT2 wheel, and the CSR wheel have this PS3 mode, so I assume they should work too.
Just thought I would give you my findings, great work, keep it up Matlo
