I’ve also got issues with the Mad Catz SFIV Arcade Stick (identified as MadCatz PC USB Wired Stick 8818 by jstest). If I connect it to my Ubuntu 14.04 desktop and use jstest, all buttons work fine. When I connect it to my raspberry pi 2 with either raspbian wheezy or retropie 3.1, none of the buttons react in jstest. It is detected fine, and /dev/input/js0 is available, but none of the buttons work. Anybody got an idea what is wrong?
