I contacted steam support a few days ago but they haven't answered. I'll post what I sent them here: Hi there. I'm pretty new to Steam and I opt to use a wired Xbox 360 controller whenever I can. There's only one problem. For games like Left for Dead 2, Stanley Parable, or CSGO, the game thinks the Start and Back buttons on my 360 controller are actually my Right and Left Stick buttons, respectively. For example, if I want to pause the game, I'd have to press the right stick to do so. Naturally, I thought I'd just change this by going into the controller configuration options in the menus by remapping buttons, but there is no option to remap the Pause button in any of those games. It's the only button that these games don't allow you to remap. I'm on a Macbook Pro, by the way. Games like Fez and Hotline Miami don't have this problem though. So maybe it's a problem with games running on the Source engine? I'm not sure, I'm very new to this. Either way, this is a pretty annoying problem. If I knew the slightest about computers, I could probably fix it by going into a bunch of hidden files and messing with things, but I really have no clue what I'm doing when it comes to that type of stuff. So again, the only problem I'm having is the Stick buttons switched with the Start/Back buttons. Is there an easy fix? Thanks.
