I received the Xbox Series X/S controller today! It's really nice but unfortunately at first view it only support BLE. (PS5 Dual Sense is still BR/EDR (aka. BT classic)).
Support for this controller will need to wait for me to add the BLE support which will also enable using BLE keyboard & mouse and the Steam controller.
Checkout the Android trace & HID descriptor for the new Xbox controller here.
The descriptor is a mix of the Xbox One controller xinput and dinput descriptor. Look like microsoft is moving away from Xinput. Report 1 & 3 closely match the dinput one, report 2 & 4 are added from the xinput one.
Other than that I ordered some new cables PCB for making PSX cable and ordered 20 BlueRetro DevKit assembled boards for the Beta. I also received most of the extension cord required for building the cable adapter for the Beta.
