Fixed bug 4477 - Support more than 4 XInput-capable devices on Windows Jimb Esser Add new RawInput controller API, and improved correlation with XInput/WGI Reorder joystick init so drivers can ask the others if they handle a device reliably Do not poll disconnected XInput devices (major perf issue) Fix various cases where incorrect correlation could happen Simple mechanism for propagating unhandled Guide button presses even before guaranteed correlation Correlate by axis motion as well as button presses Fix failing to zero other trigger Fix SDL_HINT_JOYSTICK_HIDAPI not working if set before calling SDL_Init() Add missing device to device names Disable RawInput if we have a mismatch of XInput-capable but not RawInput-capable devices Updated to SDL 2.0.13 code with the following notes: New HID driver: xbox360w - no idea what that is, hopefully urelated SDL_hidapijoystick.c had been refactored to couple data handling logic with device opening logic and device lists caused some problems, yields slightly uglier integration than previously when the 360 HID device driver was just handling the data. SDL_hidapijoystick.c now often pulls the device off of the joystick_hwdata structure for some rumble logic, but it appears that code path is never reached, so probably not a problem. Looks like joystick_hwdata was refactored to not include a mutex in other drivers, maintainers may want to do the same refactor here if that's useful for some reason. Something changed in how devices get names, so getting generic names. Had to fix a (new?) bug where removing an XInput controller caused existing controllers (that moved to a new XInput index) to get identified as 0x045e/0x02fd ("it's probably Bluetooth" in code), rendering the existing HIDAPI_IsDevicePresent and new RAWINPUT_IsDevicePresent unreliable.

Fixed bug 3299 - DirectInput: Incorrect joystick mapping when attaching new joysticks Jimb Esser Note: This is using DirectInput, I have to disable XInput as that causes all but the first 4 controllers to be completely ignored by SDL (I can find no way to reconcile XInput devices with DirectInput devices, otherwise I would make a patch that accepts the fifth and later controllers with DirectInput...). XInput does not seem to have the problem below, only DirectInput. I plug in 3 identical wireless Xbox 360 controllers, call them J1, J2, J3. Direct Input shows them as having GUIDs G1, G2, G3. I unplug J1, then J2 and J3 show up as having GUIDs G1 and G2! Not so "unique"... I start my SDL app when just J2 and J3 are plugged in, and open J2 and J3. Then I plug in a new controller, SDL sees that now G3 exists, assigns that a new SDL joystick instance ID, which I request to be opened, but G3 at this point is J3, which I already had opened! So I end up with two instances of J3 opened, and none of J1. "Re-"opening G1 would get the actual handle to the newly attached controller, but there's no current way to know this. This is clearly a bug or poor design in DirectInput or my wireless receiver drivers, but is a showstopping bug for my 8-20 player games (as soon as any one controller runs out of battery or goes to sleep and gets turned back on, suddenly things are busted requiring a restart (or, at least, a reinitialization of all controllers - the game can't go on)). The solution I found is to use HID paths instead of GUIDs to uniquely identify joysticks. GUIDs are still needed to open a controller, however I have added code to re-find the GUIDs for all joysticks whenever a new joystick is attached or removed. This does now require opening of all joysticks (instead of just enumerating them), though if your app, like mine, is opening all of them anyway so that any can press a button to join, that doesn't change much (although perhaps they joysticks should be kept open in this case, instead of closed and re-opened). If your app only ever opens one joystick, this will do more work at startup than it did previously.
