Hello Folks, My windows 7 laptop will not recognize my phone. I have tried three different USB cables, downloaded Samsung Kies, and the drivers direct from TMobile and Samsung, yet my phone will not sync with computer. The message pops up and says "USB Device Not Recognized". The computer knows that it is plugged, since the message pops up, and I have tried with and without debugging mode on. Anyone have any tips/downloads/ideas to get my computer to recognize the device so it can be rooted? Thanks for your help ahead of time.
