Xbox 360 controller not recognised in N64 games

Hi, Sorry if this is a stupid question, but I am a newbie. I have installed lakka RPi2.arm-2.2.2, and I have a official xbox 360reciver an controller, which work with other roms. When I launch a N64 game, any, I get a “no controller” message. I am running the N64 games with the default Mupen64plus. Any idea?
