This is super frustrating - when connecting my Droid to my PC via USB, it is CONSTANTLY disconnecting/reconnecting. And it loves to do this when I'm trying to transfer files. I hear the USB disconnect and reconnect sounds at least once every 10 seconds, sometimes in very rapid succession. I cannot transfer anything anymore, and it's driving me insane. I have 6 USB ports, and all have the same results. None of my other USB devices have this problem.
