Here are two more SniffUSB traces for the CanoScan 8800F.
1) The result of asking for "replug" of the scanner in SniffUSB
2) The result of scanning a 2inch wide by 1inch high white sheet of
printer paper at 75dpi using the Canon utility for this (limitation is
that smallest value is 1 inch), after a SniffUSB "replug" (4.9MB
unzipped), please find it at:
I need to look at these files carefully now and see if as Stef
suggested there might be some firmware passed to the scanner. I also
haven't figured out yet exactly what is the data: I see only two
reasonably-sized chunks passed back by the scanner---three chunks of
1024 lines (of 16 data each), and one chunk of 173 lines.
Sorry, but I am also still in the process of reading up on USB protocol.
