find my phone
I am searching as well and found specs which referred to PC SYnc: USB 2.0 (My Phone)
Try re-botting the phone; without switching it off take? the battery out for a few mins and then switch it back on.
Go into the connectivity menu and ensure you have select Mass Storage mode before connecting the USB cable. Then connect the USB cable and try again.
Hope this will help you.Thanks,
