title: Joystick Controller works on Editor but not on Builded Game
body: <p>As the title suggests, I have connected a usb controller into unity of which worked perfectly. I mapped the specific keys to be used and its working without a hassle. However when I builded my game and run it, my controller doesn't work on it anymore. I tried editing the Inputs on the startup page of the game (where you can edit the graphics etc), I tried assigning a button on the inputs by double-clicking it, it doesn't read my controller's input no matter what button I press.

  It's not my controller I think that's wrong since I can play other games using it. I tried FEZ and the moment I plugged my controller and started the game, the game immediately detected it and changed its controls from keyboard to controller. It works on Unity's Editor, but on the final build it doesn't even detect it.

  How can I fix this?</p>
