I'm using a Saitek X52 and a Steam Controller, when loading ArmA and going into the Controls > Controllers section the joystick is no longer listed, just my Track IR and an XBox Controller (which is the Steam Controller).

If both devices are plugged in (and visible within Windows) ArmA will ignore the joystick and just find the controller.

I would like to be able to use both devices at the same time because:

1. The Saitek is awesome for flying helicopters and planes with
2. The Steam Controller is good for driving vehicles since it has analogue-style controls.
3. The keyboard is horrible for driving vehicles and the joystick feels 'wrong'
4. Steering wheels are far too bulky to attach and detach
