I have heard that you can connect two wireless Xbox 360 controllers plus an old Madcatz fightstick which should work although I have not tested this yet.
Both controllers are recognized by Steam but not individually recognized by MvC: Infinite.
Have you tried direct input vs wireless? Also can you confirm this works with xbox 360 controllers? So far I have tried old PS3 Madcatz TE fightsticks vs Xbox 360 wireless controllers and was unsuccessful.
