I have an Arduino Uno R2 which in the past has worked fine, however just now I plugged it into my windows 7 computer and its not recognised at all, not even as an unknown device, it doesn't appear at all under device manager.

Arduino not recognised

I am having the same problem with an XP operating system.

Apparently this is a common problem, but no one seems to have an answer.
