I've been trying to sync my phone with my work computer for the past several days with no luck. I was able to sync using HTC Sync when I first received the phone but now I can't even get it to enter USB Mode. I was using the usb cable that came with the phone when I initially sync'd it, but since then i have picked up an additional charger/usb cable from my local authorized verizon dealer and can only charge the phone when i plug in the phone to the computer. I tried uninstalling and reinstalling HTC Sync and then installed the latest version of HTC Sync with no luck. I'm thinking that it might be the usb cable that i'm using (since i was able to sync before), but not sure if its something else (lack of driver or something like that).
