My iPod Nano 7th gen is not recognised by either PC or iTunes

So I just downloaded some new MP3 files and was looking to connect my 7th gen iPod Nano to my PC to sync them on.

Upon connection, I recieved a message from iTunes saying:

"An iPod has been detected, but it could not be identified properly. Please disconnect and reconnect the iPod, then try again. If the problem persists, uninstall iTunes, then install iTunes again."

Not only have I disconnected and reconnected the iPod more times than I can count, I have stopped the iTunes service once, restarted my PC twice, reset the iPod four times, unplugged my printer's USB, checked the cable (it is the original iPod cable) and a whole host of other things in order to get it to work. I still cannot get my PC or iTunes to recognise the iPod.

Please, any ideas? I'm really stuck here...
