USB scanner fix

This is just to send a great thank you with links and page rank to Jory Anick for the three short paragraphs on the USBScan fix page that finally got my new Canon PIXMA multifunction machine to scan. I really was just about to send the whole thing back to Canon for a refund.

That's apparently the sort of punishment you can expect for trying to work out what Windows Services you really, really need. Are they all documented somewhere?
