How to enable Device tracking for Motion Controller components?

Hey, I am currently working on a VR project and created for that a custom MotionController Actor. This MotionController is instantiated by a AC_MotionController component on BeginPlay. I added a AC_MotionController to my VrPawn for each hand. My my issue is that the controller always returns a world transform of 0 and is not rendered. If I add the built in MotionControllerComponent to my VrPawn, everything works as intended though.

My MotionController component tree:

Its BeginPlay Event:

How how do I enable the tracking of my physical motion controllers in my MotionController Actor?
