I just took my nano outta the box this morning and it isnt working. I plugged in the usb to the back of my comp. Updated my iTunes to the newest version and then plugged in my nano. Didnt start to charge or even pop up in my computer. I moved the usb plug around, tried it in 2 other spots. Didnt work. Restarted my comp. Didnt work. Not sure what else to do at this point since the nano hasnt even gotten its first full charge.
