Cannot sync iTouch. {"One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it."}

Any help? I have not synced the iTouch in quite a while because it could not be found after an out-of-state move. I just found it, after two years, and am wondering if it will sync if I Restore it. I don't want to lose all of my music and if there's a way to avoid that, I would appreciate it the recommendation.
