This is a project to write a SANE driver for Canon's CanoScan FB630U (and similar) USB scanners.
The beta code from this project was integrated into SANE 1.0.8 (released on 27th May 2002) and development at this end has since stopped.
Here's an image scanned using version 0.0.1 of the software.
Simon dismantled his FB630U to see what chipsets were used in its construction, since Canon were unwilling to divulge any technical specifications. The following information is as much as we know to date.
The following documents have also been used for familiarisation with the USB protocol and its support under Linux.
