Currently there are two input managers that expose the full capabilities of the AllyX controller. InputPlumber and a kernel patched using the new ally x driver, and HHD. InputPlumber is fully integrated into OpenGamepadUI and provides the most integrated experience with it, but we also have a fallback that should work okay with HHD (hasn't been tested as far as I'm aware). There are some limitations to that approach however. Primarily, there is a bug in the Godot event detection that prevents some functions from working. You'll also lose access to the per game input profiles and will need to use HHD's UI to manage what it provides for that.
