I have an HTC Desire and want to connect it to HTC Sync which I have installed on my computer today, from the HTC site. When I plug my phone into the USB on the computer, nothing happens. If I double click the HTC Sync desktop icon, Sync launches but says "No Device Connected" I have tried 2 USB ports which I know work. The USB lead seems fine to me as the phone charges when plugged in to the PC. Any thoughts guys? Thanks.
