When I plug in the usb for the PS3 Street Fighter IV fightpad it automatically installs the drivers.So i go onto GGPO 3S and i try to set up my controls with the pad.Then it says that another button is being held down and i’m postive sure that nothing else is being held down then the button im trying to set.I’ve calibrated it.I’ve been searching all day.So could i get some help?
