iOS: Device not recognized in iTunes for Windows
I would start with:
Removing and Reinstalling iTunes, QuickTime, and other software components for Windows XP
Removing and reinstalling iTunes, QuickTime, and other software components for Windows Vista or Windows 7
it works for win 8 too
There could be a problem with the drivers in the computer. Try what lllass said, and if that doesn't work, call Apple or go to one of there stores.
