Did you ever have another LG device that you connected to your computer. I have this same issue. Every time I get a new phone (first my optimus, then my connect and now my motion), I have to COMPLETELY remove all my old drivers from the previous phone or the new one wont connect correctly. Just search LGs website for the newest drivers for this phone. Go into your control panel --> programs and features and uninstall anything with LG on it. Then reinstall the new drivers, connect phone when done, WAIT for windows to completely finish synching the device with the drivers, and you should be all good.
