iPod not showing in iTunes after multiple unstall and reinstall

A few months back I plugged in my iPod to listen to it via iTunes on my laptop. No problem.

Today I went to do the same and it isn't even showing in iTunes now. I have unstalled iTunes, reinstalled it. Used a different USB cord for my iPod. Used a different dock and the whole shebang.

What is going on with iTunes and is there anyway to connect the two again?
