We'll default this off for now, since we don't detect whether the controller is running firmware v1.03 and don't have a fallback for controllers running firmware v1.02 (the out-of-box firmware)
We can't use keyboard input as a signal about whether a keyboard is attached. There might be keyboard input from any number of generated inputs or non-keyboard devices.
SDL_IsGamepad() calls SDL_GetJoystickTypeForID(), which will call SDL_IsGamepad() if it's not a known controller type. The new code which is breaking was added to prevent Logitech FFB wheels from showing up as gamepads, which we check for separately.
On Windows 11, apparently HidD_GetManufacturerString() and HidD_GetProductString() can return TRUE without actually filling in any string data.

These changes enable the Logitech G29 wheel to run on hidapi with both SDL_Joystick and SDL_Haptic interfaces.
While it is already possible to use the wheel on Linux in WINE + SDL2 thanks to the in-tree evdev driver as well as new-lg4ff, these set of changes allow the G29 to be used with WINE under MacOS and FreeBSD
These wheels should also be supported, but I can only test them from G29's compat modes: G27, G25, DFGT, DFP, DFEX
Haptic and led support are ported from https://github.com/berarma/new-lg4ff
It looks like both macOS (15.1.1) and SDL are trying to talk to the controller at the same time, which can cause interleaved replies or even locking up the controller. Waiting a bit before talking to the controller seems to take care of this.
This can happen on Windows when the controller is turned off directly. It still shows up in the device list and you can send packets to it, but it's off and doesn't respond. We'll mark this device as broken and open the other as a single Joy-Con.
This was intended to make the API public, so SDL_hashtable.h got an extreme
documentation makeover, but for now this remains a private header.
This makes several significant interface changes to SDL_HashTable, and
improves code that makes use of it in various ways.
- The ability to make "stackable" tables is removed. Apparently this still
worked with the current implementation, but I could see a future
implementation struggle mightily to support this. It'll be better for
something external to build on top of the table if it needs it, inserting a
linked list of stacked items as the hash values and managing them separately.
There was only one place in SDL using this, unnecessarily, and that has also
been cleaned up to not need it.
- You no longer specify "buckets" when creating a table, but rather an
estimated number of items the table is meant to hold. The bucket count was
crucial to our classic hashtable implementation, but meant less once we
moved to an Open Addressing implementation anyhow, since the bucket count
isn't static (and they aren't really "buckets" anymore either). Now you
can just report how many items you think the hash will hold and SDL will
allocate a reasonable default for you...or 0 to not guess, and SDL will
start small and grow as necessary, which is often the correct thing to do.
- There's no more SDL_IterateHashTableKey because there's no more "stackable"
hash tables.
- SDL_IterateHashTable() now uses a callback, which matches other parts of SDL,
and also lets us hold the read-lock for the entire iteration and get rid of
the goofy iterator state variable.
- SDL_InsertIntoHashTable() now lets you specify whether to replace existing
keys or fail if the key already exists.
- Callbacks now use SDL conventions (userdata as the first param).
- Other naming convention fixes.
I discovered we use a lot of hash tables in SDL3 internally. :) So the bulk
of this work is fixing up that code to use the new interfaces, and simplifying
things (like checking for an item to remove it if it already exists before
inserting a replacement...just do the insert atomically, it'll do all that
for you!).
It turns out the mapping we include doesn't work for real controllers, and they're using a generic chipset and generic name and can't be generally distinguished from other controllers.
See https://github.com/libsdl-org/SDL/issues/8644 for details.
The LED hint was getting registered for SDL_HINT_JOYSTICK_ENHANCED_REPORTS
instead of SDL_HINT_JOYSTICK_HIDAPI_PS5_PLAYER_LED, which results in a
use-after-free followed by a crash.
