Hi SaviorNT,
Unfortunately this has been marked as out of scope for the current direction Epic is taking with UE4. While there is a possibility that this will change in the future, direct input controllers will not be a feature added into the engine anytime soon. It is possible that a developer with access to source may be interested in taking on the challenge of implementing functionality for direct input controllers, I would recommend inquiring in the Github or C++ sections of the forums to see if there is interest!
