Plug my iPod in at home on my 5-year-old G4, and it semi recognizes it. It plugs in and shows my songs, but everything in iPod Summary is greyed back, and once disconnected, my iPod is brand new... no songs or anything in it. iTunes wipes it clean. I tested it at work and it's not the iPod, also took iPod to the Genius Bar, nothing wrong. Anyone have the same issue?
