I have the TrackIR 5 and while it works well most of the time, it frequently will loose it's center and start "looking" all over the place. When it's doing this, the left hand green LED is off or intermittent. It doesn't seem to matter which sim I am playing, it just randomly does it for no apparent reason. It even does it in the TrackIR program. I make sure there is nothing interfering with the IR signal and the reflectors are in place on the hat clip. I use to have the TrackIR plugged into a USB hub. I plugged it directly into an open USB port but it still does it. Anyone else have this problem and maybe know what to do about it?
