The Mad Catz Saitek Heavy Eqpt. Wheel & Pedal and Side Panel Control Deck detect under Proton Experimental/8.0-4/7.0-6/GE-8-4 only the steering wheel and this was unusable. Steering was only possible to the right and this was also the case with the pedals (only one axle). On Proton 6.3-8, both controllers were correctly detected by the FS 22 and the axes were also assigned correctly.

The Report from Ω Compu brought this to my attention.
