@tonythetiger giving people more info to be able to help you really helps. There is a link at the top of every page that tells you what info you need to provide. You agreed to this when signing up. You provided no info on your setup so no one would even know how to help you. You can bump a thread but please dont open multiple posts on the same issue. If you had mentioned that you had a ps3 controller people might have been able to tell you to uninstall the ps3 driver, setup both wii u controllers so they are working correctly, then reinstall the ps3 driver. You cant be mad at people for not helping you if you dont provide info.

Did you wire your joystick properly? What kind of joystick and USB encoder do you have?
If buttons can be configured but joystick is not responding than probably joystick is not compatible with usb encoder (if you bought whole kit with encoder and joystick it's probably not possible) then you haven't wire whole setup properly.
But give us some more details or post some photos.

@columboscoat thank you
