Left 4 Dead 2 gamepad problem

Ello

I have a problem in my game left 4 dead 2. I enter the game set up splitscreen and make for 2 players. Yes i got 2 gamepads, not xbox 360 butsaitek rumble pad. :oops:

Problem

the problem is, when i start the mission, and check the gamepads, the first gamepad has everything okay, but when i check the second, it doesnt respond to the keys listed, like button for fire, i press it but it doesnt fire, when i check other buttons, one of them is the button for fire. But i cannot see controlls set up for 2 player...

please help
