Dear Mo,
Did you do all the updates after SP2? Do those first.
For a big-bang USB fix. Open Control Panel / System / Hardware /
Device manager and uninstall all USB root hubs. (Don't panic - they
all come back after a reboot). I find this an excellent way to clean
up a confused USB driver chain kernel table.
Note: unplug ALL USB devices before doing this - then put them back in
3 Minutes after the reboot - ONE at a time. One of these will be your
iPod, and it should install nicely.
Hope that helps.
