I got a Logitech Wireless Gamepad F710 which is use to play games on Steam (Big Picture mode). This works for the most part great. Sometimes I have to use the xboxdrv emulator to make games behave correctly (Trine 2). But in Left 4 Dead 2 the two analog sticks does not respond at all. This is a bit strange because all digital input works. I can jump, fire the gun, turn on flashlight etc. Even pushing down the analog stick works, but I can not move around. I have tried the xboxdrv emulator with the same result. Does anyone else experience this?
