i currently have windows vista 64 home premium on my laptop. i recently received ipod nano, 5th generation. i downloaded current itunes version but computer will not recognize ipod when plugged into usb port. tried my other 2 usb ports and still will not recognize. i plugged my ipod into my sons computer which runs windows xp and it recognized it. my usb ports are working cuz i can use other devices. i am so frustrated. Apple and dell are no help what so ever. i have removed itunes software twice and still nothing.
