xbox 360 gamepad not working

[michael.lc]

Hello I'm a newb in the forum
just tried donlphin tonight and got supermario bros (EU), it's running well, but my problem is the xbox360 gamepad, I can map the keys in the Dolphin GCPad configuration and it recognizes my pad, but when i started the game, the game pad is just not functional.
It's displayed as XInput/0/Gamepad
