OK. Many thanks for your report.

Please sniff the USB protocols from a small scangear adf scan, e.g.
10x10mm @ 75dpi with wireshark.
And again in a different log file from Sane in a Linux terminal:

(1) $ export SANE_DEBUG_PIXMA=11
(2) $ scanimage --source "Transparency Unit" -l 100 -x 10 -y 10 2>
pixma.log > pixma.pnm

Then I can compare both log files and prepare a patch.

OK. I can prepare a Patch for 1200 dpi. XSane shouldn't show the option
for 2400dpi.

Please zip the log files. The mailing list rejects large emails.

Cheers,
