So there are multiple buttons not working on the throttle , i can not bind them and they do not show as working buttons in the controller settings.. I have taken it apart only to see if there were visually something wrong or unplugged. i found nothing .. the buttons that are working on the throttle are : The hat switch, the “E” button,The “I” button, The “D” button . And the mouse switch button the mouse its sell works fine. all rotaries are working fine the buttons by the mdf work fine and the throttle axis works fine.
