The 8BitDo SF30 Pro Gamepad will generate a single motor pulse for each rumble message, so we need to do this frequently to have continous rumble on this device.

When I run SDL_INIT with SDL_INIT_JOYSTICK it stalls for about 10 seconds (last report was 10,615ms), but only if I'm currently playing audio. (Like in Spotify for example.)
querying something related to device access (last dll loaded)
'BabbysFirst64.exe' (Win32): Loaded 'C:\Windows\SysWOW64\deviceaccess.dll'.
I use a USB DAC because my mobo's audio out is pretty not great. And I've noticed unplugging it seems to solve the issue. I haven't noticed any other issues that are caused by my DAC.
My DAC is the Sound BlasterX G1 https://us.creative.com/p/gaming-headsets/sound-blasterx-g1
Vid = 041E
PID = 3249
My system specs:
- Windows 10 Pro
- Ryzen 2700x
- 16GB Ram
- Nvidia 2070 RTX
Additional USB devices plugged in:
- Valve Index
- Xbox One Elite Controller

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.

In SDL_hidapi_switch.c
line 443: Function BTrySetupUSB call WriteProprietary with pBuf=NULL and ucLen=0
line 376: WriteProprietary check its input (!pBuf && ucLen > 0) || ucLen > sizeof(packet.rgucProprietaryData): ucLen is 0 so it passes
line 382: WriteProprietary call memcpy with pBuf=NULL

Dualshock4 on bluetooth need 78 bytes for the rumble data while SDL_HIDAPI_RumbleRequest can only hold 64 bytes.
'volatile' is not meant for thread synchronization.
The list of rumble request could grow infinitely if user call SDL_JoystickRumble too much. The documentation says "Each call to this function cancels any previous rumble effect", so overwriting pending request seem like a good idea.
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.
This sequence works across Microsoft, PowerA, PDP, and HORI controllers.
The newer Microsoft XBox firmware requires synchronizing the rumble sequence number, when SDL sees it after the initial connect
The Razer Wildcat controller requires waiting for init responses before continuing the initialization sequence.
The PDP Battlefield 1 controller takes over a second to be ready for initialization, and if initialization is attempted before then, it will fail.
Using Wii U GameCube USB adapter with multiple controllers attached and
restarting SDL input in a game results in extra joysticks with NULL name.
HIDAPI_CleanupDeviceDriver() shut down joysticks by iterating through
device->num_joysticks but each HIDAPI_JoystickDisconnected() decreases
device->num_joysticks and shifts joysticks array down. Resulting in only
half of controllers being shutdown. It worked with only 1 controller
attached though.
Disconnect HIDAPI device joystick 0 until there are none left.
Added the functions SDL_JoystickFromPlayerIndex(), SDL_JoystickSetPlayerIndex(), SDL_GameControllerFromPlayerIndex(), and SDL_GameControllerSetPlayerIndex()
