A variable containing a list of devices that are not flightstick style controllers.
Defined in SDL_hints.h
#define SDL_HINT_JOYSTICK_FLIGHTSTICK_DEVICES_EXCLUDED "SDL_JOYSTICK_FLIGHTSTICK_DEVICES_EXCLUDED"
This will override SDL_HINT_JOYSTICK_FLIGHTSTICK_DEVICES and the built in device list.
The format of the string is a comma separated list of USB VID/PID pairs in hexadecimal form, e.g.
0xAAAA/0xBBBB,0xCCCC/0xDDDD
The variable can also take the form of @file, in which case the named file will be loaded and interpreted as the value of the variable.
