Has anyone ever had a USB port on their Macbook Pro suddenly go dead?

I was just wondering whether anyone using a MAcbook Pro Retina has suddenly had one of their USB ports die on them? My one port does not seem to recongise any peripheral hardware I attach to the port and I am confused why this should have happened. Apart from the obvious reason which is probably that the USB port has died I was just wondering whether this is a common fault with these machines and if it is, whether someone else may have a few words of wisdom related to how to solve the problem. The machine is not even 6 months old so I am reluctant to simply write this off to a failed USB port which will be the first time this has ever happened to me. I would value any input.

Hi C,
You have a one year warranty and I would definitely bring this to Apple for diagnosis and repair.
