I had my iPod touch unplugged while I was laid up. Naturally the battery died. I plugged it into the computer and recharged it. Then I got a notice of a new version of the software. I attempted to download it, but I got hung up and now the screen shows an itunes symbol with an arrow coming from the image of a USB connector. I have the Ipod connected to the computer through a hub but it is not recognizing the iPod? Any ideas out of this predicament would be appreciated.
