I've used multiple usb hook-ups so I know its not a bad cable. I've tried searching for the device/ adding it manually nothing will work. I've also tried using different USB ports, no luck. Need help from somebody smarter than I!!
I had to play with my wife and daughter's Android phones (HTC Inspire) to get Win7 to see them. I installed the HTC software and drivers, then applied an update, then ran the S/w install, then attached the USB cable, went to config on phone and started the sync. It took many tries but I finally got it to work.... Good luck!
i thought i tried everything under the sun. if kies or just the usb drivers are not fixing it for you try plugging into a different usb port. i've been at this for hours and this is what has finally worked for me. kies is part of the fix as i tried switching usb ports before with no luck.
