Ok I have searched for a few days, and read every post and I still cannot figure this out. when I run retropie_setup.sh, and select SETUP, instead of finding the joypad (I have a logitec rumblepad 2), it finds nothing and says (and I quote) “The configuration file has been saved as .cfg and will be used by RetroArch from now on whenever that controller is connected”

I can get it to work if I configure it each time for each game, but that is a pain. what am I doing wrong?
