It seems to be happening with the same frequency now, even with the device listed above disabled. I can check the USB power but I don't believe that will help as I think I've tried that before. It seems to be literally whenever the system scans for a new device. It has happened on every computer I've ever had since 2.0 came out.. and that's 4 computers with multiple controllers. Wired, wireless.. I just can't get it to stop. I'm growing tired of running off a cliff for no reason.
