We know, you have mentioned that fact more than once :-)
But what's the connection to the article about the Canon D660u you are
responding to? As you yoursef wrote, the visioneer 5800 uses a
Realtek, not a National Semiconductor chip.

Have you already asked Realtek about programming information for that
chip? What about Visioneer?

Have you read the documentation you have been ponited, to? E.g. 

In your case I'd start with trying to capture the USB commands send to
the scanner using one of the methods explained in the docu.

You know that the HP ScanJet 3530C uses the same (similar?) chip? See
http://www.cscs.ch/~tack/hp3530.html . Maybe you can work together?
