Hmm, ok then. I know it isn't a port issue but just out of curiosity try another port, this shouldn't be happening. This is not an issue with iTunes, or the cable, you say it charges the iPod when plugged into an outlet. The port works for other devices, so it's not the port. And the iPod cannot connect to iTunes in its current state so it's not iTunes. Try other ports just for the heck of it, it's gotta be something with the computer or the cable. Try other ports and if yup have another cable try it to. It may be a bad wire in the cable, it can charge from an outlet but the data portion may be bad.
