Hi, I have a RGHed Xbox 360 Phat, lately I discovered my LB button only respond to short clicks but not when held down, I thought it was the controller so I purchased a new one, same issue, so I tried other controllers, all had the same issue, so I tried connecting a 2nd controller at the same time, worked fine. It seems no matter which controller I use, as long as it is connected as 1st controller the LB button doesn't work right. Any idea why is that and how I can fix that? Thanks
