I have an annoying issue on MacOS about XBoxOne Bluetooth rumble (Vendor: 0x045e, Product: 0x02fd).
When 360controller is installed, rumble is working correctly. However, Bluetooth rumble isn't working at all, with or without 360controller installed (although it is working with Chrome + https://html5gamepad.com).
I looked at the code, and it seems that XBox controllers are managed in MacOS in this file: SDL_hidapi_xbox360.c. The XBoxOne file is disabled for MacOS in SDL_hidjoystick_c.h.
The function HIDAPI_DriverXbox360_Rumble() is called correctly, and hid_write() returns no error.
I have tried a stupid test. I took the rumble packet from 360controller: ec4e88eb2d/XBOBTFF/FFDriver.cpp (L620). With the patch I have attached, I manage to have rumble working on Bluetooth (with some stupid vibration level, but it proves it can if the packet is changed).
But it breaks the USB rumble with 360controller. A comment in the function makes an explicit reference to 360controller, I think that's why I have broken this specific usecase.
I don't know what is the correct way to fix this, but it seems that the current implementation has a missing case for Bluetooth support.
Note that I also tested master this morning, and I have another issue:
if (!device->ffservice) {
return SDL_Unsupported();
}
test fails in DARWIN_JoystickRumble(). This test has been done quickly, I'm not totaly confident about its accuracy.
There is now a thread that handles all HIDAPI rumble requests and a lock that guarantees that we're not reading and writing the device at the same time.
Added the functions SDL_JoystickFromPlayerIndex(), SDL_JoystickSetPlayerIndex(), SDL_GameControllerFromPlayerIndex(), and SDL_GameControllerSetPlayerIndex()

On a Dualshock 4 controller using hidapi driver, calling SDL_JoystickRumble with a duration too long (SDL_HAPTIC_INFINITY for example) causes the rumble to stop immediately.
This happens because of integer overflow on line 301 of SDL_hidapi_ps4.c
(https://hg.libsdl.org/SDL/file/a3077169ad23/src/joystick/hidapi/SDL_hidapi_ps4.c#l301), which sets expiration time in the past.
It causes the HIDAPI devices to always be opened on enumeration, which causes crashes in the Windows drivers when multiple applications are reading and writing at the same time. We can revisit this after 2.0.10 release.
The Nintendo USB GameCube adapter has four controller ports. Return
the port number as 0 to 3 from SDL_JoystickGetPlayerIndex() and
SDL_JoystickGetDevicePlayerIndex().
Note that a single USB device is responsible for all 4 joysticks, so a large
rewrite of the DeviceDriver functions was necessary to allow a single device to
produce multiple joysticks.
