The fix is very fast and simple. Launch NBA 2K15 in Steam's Big Picture Mode. This is located in the top right of steam, to the left of the minimize button. Have your controller plugged in, then go to library-NBA 2K15-launch. Proceed to your game. Steam's Big Picture mode is designed SPECIFICALLY for controllers. This will ensure that your controller works fine. That's it! Your controller should now work in every game mode, including the park!
