As all we know, XBox has a mouse/keyboard support. But why you didn't apply this option? To be honest, keyboard is working well - WASD, Shift, Spacebar and oher keys, eccept ability to change keys layout, but mouse do not work at all. For now i have to use Venom-X to play. I don't think, that it's too hard for you, to implement this future to your game. A lot of people will thank you.
