Hi Bastien,

I prefer to keep the various names in the commit message, just so that
it's easier to find the commit later when searching for the patch.
I found that various teams refer to various controllers in a different way.
Happy to rename the variables in the code, though.

How about something like:
USB_DEVICE_ID_MS_XBOX_CONTROLLER_MODEL_1708
USB_DEVICE_ID_MS_XBOX_CONTROLLER_MODEL_1708_FIRMWARE_2021
USB_DEVICE_ID_MS_XBOX_CONTROLLER_MODEL_1914
?

I tested this on an Android device, with a simple rumble test app that I wrote.
A better way would probably be to write some EV_FF events to
/dev/input/eventX node.
You could try the "python-evdev" module, which provides a sample rumble script:
https://python-evdev.readthedocs.io/en/latest/tutorial.html#injecting-an-ff-event-into-first-ff-capable-device-found
I haven't tried that since there's no python on Android.

Here's the list of controllers where this could also work:

Controller VID PID Classic/BLE
Xbox One S 0x045E 0x02E0 Classic
Xbox One S 0x045E 0x02FD Classic
Xbox One S 0x045E 0x0B20 BLE
Xbox Elite Series 2 0x045E 0x0B05 Classic
Xbox Elite Series 2 0x045E 0x0B22 BLE
Xbox Series S|X 0x045E 0x0B13 BLE
