I have an IBM T40 laptop running XP Pro and two iPods, a 3G and a 1G nano. Ever since I updated iTunes a while back, the computer wouldn't recognize the nano, said it needed to be restored, etc. At some point I started getting the 1418 error
. I tried a lot of different things to fix it, including:
-Restoring the nano multiple times.
-Uninstalling iTunes and reinstalling it.
-Uninstalling iTunes and reinstalling an older version of the iTunes software.
-Testing the cable (it works) and the USB ports (ditto).
-Testing whether the computer would recognize the old 3G (it does, both in iTunes and as an external hard drive in My Computer).
I finally gave the nano up as irredeemably corrupted and the Apple Store swapped it out for another one. I just plugged the new nano in and . . . same problem! In the right hand corner, it tells me an unknown device is connected. In iTunes there is nothing.
