Lately, when I've tried to connect my Ipod shuffle (2nd generation) to my computer, I get an error message "USB Device not recognized". I thought it might be my computer, so I brought it to a PC and connected it, and received the same error message. The Ipod has worked on both computers before, and this started about a week ago, which leads me to believe that it may be the actual Ipod itself. Everywhere I've looked, the troubleshooting guides all start with the assumption that Windows at least recognizes the Ipod as a USB device, so they've been no help. Any suggestions?
