Just found this out after the latest June update that Valve Steam pushed out. There are now 2 versions: Steam Beta Update and Steam Families Beta. When you launch Steam it is in default mode which is No Beta Chosen. The biggest problem is that if you are using generic controllers and sticks..aka arcade controllers they will not show up as being mapped with specific device id's you intailly had assigned them. If you switch the interface to one of the versions I mentioned above Steam Will close and restart to do a new install of that version...'then get this', once it restarts then your generic controllers and devices will show up and will work. The main point is GameEX will no longer work with Steam since it has to sign you in each time you launch a new game, so when GameEX signs you in it will still work normally by launching the game, but your generic controllers will not be listed for you to use them. Here some pics if that helps. There is no way to lock the version you want to use permanently, and you have to manually remap everything...it's crazy
