Figured out a way to connect xbox elite 2 controller to zen without a microsoft Bluetooth dongle or a original xbox controller.

Plug in ur controller into a2 slot. While wired to a2 slot click the left button on the zen to start searching. When u see it blinking blue connect ur controller while still wired. You might have to push the left button on the zen 2 or three times and get it to synce but when ur zen light turns solid blue u have connected properly.

If ur controller rumbles but the zen light turns green agian its not paired correctly. When zen will turn solid blue u can disconnect the controller and its paired and good to go.

Snapchat me if any questions and I can also do a live video call if u need to see what I'm doing.
