On some Logitech controllers there is an actual switch that can identify it either as an Xbox controller or a standard gamepad. You want the standard gamepad so that the triggers are recognized as buttons and not axis. My rumblepad2 has such a switch. It's similar hardware - so your might have one too.

As far as the controls - Here's my setup and it's the same as what I had when I was on xbox

Movement calibrated to left analog stick, and camera to the right, and the menus calibrated to the dpad.Hope it helps
