Regarding the Steam Controller
I was having issues in regards to connecting the Steam controller to games. It would connect to them but would just use the keyboard linked buttons. What you have to do is: 1) go to preferences in the top menu and find and check the box for Steam beta, 2) go to big picture mode, go to settings, and click on controller add, 3) go to configuration and instead of mapping all the keys go to browse configs, templates, and then gamepad. Finally works. Just not plug and play. This app probably works fine for other controllers but won’t show the Steam controller.
