I just updated my home computer to iTunes 7.1 and have had some trouble with syncing my iPod. When I first updated it, there was an error message telling me that I should plug in my iPod into a USB 2.0 port-- which is impossible for my older iMac and there are no adaptors Now the iPod was not recognized on the computer and went to a default black screen with a silver apple logo. I restarted the computer and it synced, but it looks like the battery is out. Did the new update break the compatibility with my older mac so that the computer will no longer charge my iPod!?!? Has anyone else been having problems like this? Argh. Help!
