Just bought L4D2 on Steam but I can't get it working with my Logitech Rumblepad 2 USB controller. I enabled "gamepad" in the games Keyboard/Mouse settings and tried to edit controller the buttons but I can't get it configured properly. It looks like all the all the buttons are edited the way I want them but when I try to play the game, my character just starts spinning around & doing random actions like melee and reloading. I rarely game on Mac/PC but it seems like I'm doing everything properly. Do I need to get a controller config file for the game? I also noticed that there's no camera control movement options in the keyboard/mouse setting options. Is there any way to configure Logitech Rumblepads with this game or am I out of luck? Using an early 2013 rMBP w/ Mavericks.
