The cable I use is the elite control, its cable is the same as the crosshair, very well done. Mouse and keyboard are new, I do not think that might be the problem. But yesterday I had the same problem, the sights locked, I disconnected the USB and reconnected in the crosshair, returned to work, this was repeated several times. Is it a mouse / keyboard problem or a possible bad contact in the crosshair inputs? Sorry for the bad english.
