You may want the firewire combo since I think that lets you charge up the iPod too.

When I connect my iPod using the USB cable, I get a balloon saying 'Device not recognised'.
When I tried to configure my iPod on the computer while installing, it asked to me to connect my iPod (and I had), and so I couldn't configure it. So why doesn't my computer recognise my iPod? Is it because my USB port is too slow (I don't know what speed it is) - and if so, how much do those USB 2.0 cards cost?
