Bests & Worsts Reviews from Amazon

As you can see from the other reviews, this device works very well for some, and not so well for others. Putting aside the interference problem with other 2.4ghz devices such as mice (2.4ghz wireless routers will NOT give you problems), I believe there is a single solution to almost everyone's problem, which I will outline below. After installing the device & software, I couldn't get my black wireless xbox360 elite controller to sync with the receiver. The ring light on the controller would rotate while trying to connect to the receiver. The light on the receiver would blink attempting to locate the controller. After a few seconds, the ring on the controller would stop rotating, and start blinking. A connection could not be made. After some research, I found the solution. The issue is with USB power. The receiver needs A LOT of it. If you have other devices on your USB, especially high powered USB keyboards or mice, the receiver might not work. Try removing all USB devices and rebooting your PC with only a PS/2 mouse and keyboard connected. The receiver and controller should sync up immediately, even before you finish booting into windows. This fixed my problem. If this is your problem, there are two solutions. 1) a USB PCI interface card, or 2) an externally powered USB hub (NOT BUS POWERED). I believe the receiver needs a lot of power because its capable of syncing to four separate devices. The USB on most motherboards simply isn't strong enough. Hope this helps.
