I have a VKB Sim Joystick and a Button Box, which are connected via USB.
If I get in an vehicle, it turns the steering wheel complete to the right and automatically drives backwards without touching anything on the controllers.

As a workaround I have to disconnect or to disable those two devices.

In result thes axes of the inputs are automatically mapped, but not correct, inverted or something else. It seems the Joystick Throttle is mapped to drive backwards and something on the Button Box is mapped to steering right.

And further in the UI there is nothing configurable for game controllers.
