xac_onehand connects a USB flight stick such as a Logitech Extreme 3D Pro to both USB ports on an Xbox Adaptive Controller (XAC). This is useful for one handed players to play two joystick games.
This project was inspired by an older XAC joystick splitter project. This project uses newer boards and is simplified by using QWIIC/Stemma QT to connect the boards. No soldering is needed.
