Need to check haptic use flag on libsdl2, if dolphin found libsdl2, then it add haptic to sdl init flags. If libsdl2 build without this flag dolphin silently don't show djoystick to you because SDL_Init raise error. This is DIRTY patch: https://github.com/koi8-r/Patches/blob/master/Gentoo/games-emulation/dolphin/dolphin-9999.ebuild-SDL2-missing-haptic-use.patch Reproducible: Always Steps to Reproduce: 1. USE='haptic' emerge -1av media-libs/libsdl2 Actual Results: Can use my joystick.

This should be in the portage tree soon. Please recompile it and let me know how if you run into any issues. Thank you for the bug report and for the patch as well.
Confirming the same problem with 4.0.2-r1 ebuild. Without haptic useflag on libsdl2, my joystick is not recognized.

Created attachment 394072 [details] games-emulation/dolphin-4.0.2-r1 build log I can't test 9999 version because it pulls in others dependencies than 4.0.2-r1. I already had libsdl2 installed on my system (dependency for other packages). Please have a look at the attached build log, games-emulation/dolphin-4.0.2-r1 is already using libsdl2 : > -- Found SDL2: /usr/lib64/libSDL2main.a;/usr/lib64/libSDL2.so;-lpthread > Using shared SDL2 I just rebuilt libsdl2 with haptic useflag on, and it worked.

Alright, I modified the 4.0.2 ebuild to bring in libsdl2 with USE="haptic joystick" for the package. It should be on the portage tree shortly. Once it is I'll give it a few hours for someone to confirm in this bug report that everything works out correctly and close it after. Thank you guys for your assistance in squashing this bug :)

Also, just to clarify on this regard, it's very possible another package brought in libsdl2 as a dependency and dolphin's build environment picked up on that. I find that sometimes that can be both a benefit and a drawback because dolphin can have automagic behaviour on build.
