Sam Lantinga 833f76ab7b Fixed bug 4968 - NULL passed to memcpy in WriteProprietary in SDL_hidapi_switch.c
meyraud705

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

Sam Lantinga 81256207bd Update for bug 4923 - Calling SDL_GameControllerRumble() often takes 8 ms
meyraud705

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.

Sam Lantinga 669729a8a0 Improved Xbox One controller initialization sequence
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.

Zack Middleton f0cee3edec Fix shutting down HIDAPI device with multiple joysticks
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.

Sam Lantinga a7ae9175c3 Fixed bug 4898 - No rumble because of integer overflow in SDL_JoystickRumble
meyraud705

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.

Sam Lantinga 82d2c357c3 Fixed rumble after Xbox controller initialization
When we initialize the controller it has an internal rumble sequence number, and if our rumble sequence number doesn't match that, rumble won't happen. To fix that we cycle through the range of sequence numbers, and at some point we'll match up with the controller's sequence number and it'll roll forward until it matches our next rumble sequence number.

Zack Middleton 6f63c1c37f Make GameCube controllers only rumble if both USB cables are connected
The Nintendo USB GameCube Adapter has two USB connectors. Black for data
and grey for additional power for rumble. The Wii U and other software
require both cables to use rumble. The rumble is weaker without the
second USB cable. Other than that I don't know if there is any negative
side affects from using rumble with only one cable.

Sam Lantinga d97387ccff Fixed bug 4600 - Dualshock 4 touchpad press is not detectable with SDL_JoystickGetButton
Dexter Friedman

When using a Dualshock 4 controller (model numbers CUH-ZCT1U and CUH-ZCT2U), pressing anywhere on the center touchpad does not send an SDL_JOYBUTTONDOWN event. I have verified this with testjoystick:

Repro steps:
1. Plug in a DS4 over USB
2. Compile testjoystick and run: testjoystick.exe 0
3. Press and hold the touchpad. Observe that no lime green box appears

Expected behavior:
A lime green box appears while the touchpad is pressed.

Notes:
I've attached a patch here that works on my PC and produces the expected behavior in testjoystick, for both DS4 model numbers I listed earlier.

If I understand correctly, by exposing this as a joystick button, the gamecontroller API mapping can be modified with a change to gamecontrollerdb.txt in the future.
