SDL_IsGameController returns SDL_FALSE


i got this new controller “EasySMX ESM-9013” but SDL_IsGameController() reports that it isn’t a controller.
It does work with the SDL_Joystick* functions though!

What can i do to make libSDL support this as a controller?

(Because of this it probably isn’t detected by steam)

Add its GUID with SDL_GameControllerAddMapping. Once you have a mapping, submit it to be included in the next SDL release.
