For encoders with an EnDat 2.2 interface: If the corresponding encoder
input has already been assigned to an axis in the device settings, then
the encoder is automatically detected upon restart, and the settings are
adapted. Alternatively, you can assign the encoder input after you have
connected the encoder.
