I use a Saitek X52 Pro HOTAS and I have key reassignment problems. My Hotas has a Latched clutch function for for changing profiles in flight. I turned it off to make the Button 31 an active one and the pinky switch that was the brake now isnt detected.
Saitek equipment and logitech drivers isnt a good combination. I use the Saitek / MadCatz driver set in Windows 10 and all is well now, stable flight and everything responds as it should.
