    Hey everyone,

    I just finished installation of my RetroPie and I have a strange problem.
    I can only use one controller at a time. As soon as I connect a second one, the first controller stops working.
    This behaviour can already be observed via

    jstest /dev/input/js0
    jstest /dev/input/js1

    both controllers work fine in both slots seperately, but no response anymore when I connect the second one. Also the additional button on the adapter continues to function as intended.
    Other than that everything works fine.

    Where should I start looking?


    I would start to check the connections between the adapter and the SNES connectors. Maybe there is mix-up with the connections.
