Public bug reported: Games which rely on SDL2 (and tools like antimicro) can't see the retro- bit NES controller adapter by default because SDL2 has dropped support for the old /dev/input/jsX API and udev lacks a rule to permission the /dev/input/eventX node appropriately and set the ID_INPUT_JOYSTICK flag.
The following rule (or equivalent) needs to be added to the system- provided udev rules. SUBSYSTEM=="input", ATTRS{name}=="INNEX NES Controller USB", MODE="0666", ENV{ID_INPUT_JOYSTICK}="1" I come to this conclusion because: 1. Until the mode is changed, feeding evtest with an explicit input device number results in a permissions error. 2. Globally allowing users to read joystick input poses no security risk and the data is already mirrored via /dev/input/jsX which is 0666 already. 3. Once the mode is changed, sdl2-jstest and antimicro still cannot see it. 4. Once ID_INPUT_JOYSTICK=1 is set, sdl2-jstest and antimicro work just as well as sdl-jstest and jstest-gtk, which use the old API.
