Haha haven't heard of an iPod nano USB cable driver..

Why don't you tell us what problem you're having?

I told you there's no such thing as iPod nano USB cable driver. Everything works out of the box as long as you have a USB 2 port, heck it'll work even if it's USB 1.1, just that the songs transfer will take forever.

What you need to do is download the latest iTunes from: http://www.apple.com/itunes/download/

and download the iPod Updater from: http://www.apple.com/ipod/download/

to put the latest firmware on your iPod nano. That's it. No USB cable driver.
