Can you use PS3 and 360 controllers simultaneously?

[Xeogran]

Hello there. I want to play a Gamecube multiplayer game using two controllers: PS3's and 360's. I have Microsoft Wireless Gaming Receiver and I connect my Dualshock 3 with the USB cable.

I can setup both PS3 or 360 controller for Player 1 just fine. But then player 2 cannot move, even though it seems to be configured properly. Why is that?

Greetings.
