I wasn't certain the info on the unsupported Canon CanoScan LiDE 500F was correct:
http://www.sane-project.org/unsupported/canon-canoscan-lide-500f.html On this page it says the chipset is GL841. I have given up on this scanner, so I decided to take it apart to check the chip, and it turns out the chip is a GL120. Picture of the chip: http://postimg.org/image/y53f9ekpv/ I would be grateful if someone could update the webpage, and hopefully this info may help someone else have some better luck with this scanner!
