and the device did not show up in iTunes.
If you haven't reinstalled the Apple Mobile Device Service, try that > iPad: Device not recognized in iTunes for Mac OS X

I just posted with this identical issue, though I'm having this problem just five weeks after getting my refurbed iPad 1. You didn't mention whether your iPad will recognize the wall charger... mine does not.

I would have them check out the USB port on the iPad. If you cannot get it to connect with multiple computers and multiple cables, the only thing left is the connector port on the iPad itself.
Try an apple store or call them and see if you can send it in to be repaired/replaced.
