I bought a new ipod nano a week ago because my ipod mini was messed up. I put it on my computer with my itunes that i update all the time. I was able to upload 900 songs onto my nano. It all worked fine. Now, the computer does not recognize the ipod. I am putting it on the same USB 2.0 port. I have tried resetting and forcing disk mode, neither work. The ipod charges on the computer and I turned off the option for the computer to power down the USB port. I get a message saying it does not recognize the ipod. I am pretty sure the iTunes kind've recognizes it, but it doesn't show up in the source. But, if I restart my comp with iTunes still on, it reports that a device is scripting iTunes. Any ideas?
