I'm trying to use my PSP as a gamepad using FuSa Gamepad. It makes the PSP function as a generic dual analog stick controller. It works without problems on Windows and Mac OS X. On Ubuntu 13.10, I've downloaded JTest-gtk and Joystick and it detects the controller fine. All the axes and buttons work, etc. The problem occurs when I try to actually use the controller on anything. For example, I'll try using it on PPSSPP and the controls seem to be going haywire (random things getting pressed) when I move the analog stick. Overall it just feels like the buttons/axes are all mixed up badly (pressing up makes it detect that I have 7 buttons pressed down).

What can I do about this?
