I have the same problem, the suggested fix didn't work for me.

No? Are you sure you connected the NATIVE port? (Not the programming one) Did you press the both buttpns correctly at the same time?

Yes, I did exactly as recommended, the board appears not to work.
I played around with it a little using my AVR ISP Mk2 and the chip seems fine (the 16u2) and yet the computer doesn't detect it, the only reason I can see for it not working is if the board is faulty so I'm going to get it swapped for a new one.
