I wanted to move some music onto my phone and plugged in my USB cable to my PC. It charges the phone but it does not connect to it for me to transfer files. I recall my original Moto Droid it was say "USB Connect" and I had to tap that, then it would pop up on the computer. I do not see that happening on my Charge. In the USB Settings it is set to "Mass storage". I'm not sure of any other settings to check. What do I need to do?
