winedbg backtrace

I have an arcade stick (Hori RAP4 for PS4) that I'm attempting to use with
games under wine.

If the stick is plugged in and any input is entered (buttons, stick etc) any
program that cares about XInput will crash, including Steam.

However, if I generate an SDL controller config (using a tool like SDL2 Gamepad
Tool) and then set the environment variable SDL_GAMECONTROLLERCONFIG,
everything works as expected.

Note that since this is an arcade stick, it does not present the same number of
axes and buttons as a normal gamepad. I believe this may cause some differences
if I'm reading bus_sdl.c correctly.

I have confirmed that other gamepads (ps4 and xboxone) I own do not show this
issue.

I've attached backtrace from winedbg and console log
