Problems configuring joystick

[lolbus]

So I've tried to set up my ps2 controler on PCSX2, but for some reason, it wont detect it when I try to map the buttons! I'm using a Dual Shooter 2 plus.
I know that my controler is talking to my pc because I can map it perfectly fine on Stepmania (a dance simulation emulator). I'm running Vista 32-bit.

I've tried Lillypad aswell.

Help?

Anybody? This is really bugging me.
