iPad crashed during OS update and now iTunes can't restore

I tried to update the OS on the iPad today and about 10% of the way into the installation, the installation failed. Got an error screen saying I would need to do a restore. I was also referred to a help site at support.apple.com/kb/TS1275.

Even more disturbing is that the info in iTunes for the iPad shows "n/a" for the name, capacity, OS version, or serial number. This information showed when I first got the iPad.

I tried a restore and it went through the following steps:
extracting software
verifying iPad restore with Apple
Checking with Apple
preparing for restore
waiting for iPad
a progress bar shows on the iPad but in a few seconds I got the error of iPad could not be restored because of an unknown error of 9

subsequent restore attempts get to the progress bar, but then tells me the device can no be found

I have tried the 2 button restart of the iPad but that has not helped

I have made a copy of my last good iPad back up and have it in reserve if/when needed. Fortunately I do daily syncing of the iPad

Is there a forum solution or is this an Apple solution?
