I would definitely advise against Bluetooth for controllers as it's too low in polling rate and too high in latency. If the dongle is paired to the controller via PC first then the pairing is remembered, tried it that way?
Hmm could be the first party controllers use bluetooth chips that are geared specifically for this sort of use when connected to a console
Does it work with usb cable? If so then those Xbox adapters that allow any 2.4Ghz controller to work on console may be an option?
Thought you'd ordered one?
I'm using the Tarantula the most now as the extra buttons have been remapped to activate RTSS/NVApp etc without touching the keyboard.

Do you mean stick grips?
