[sane-devel] canon_dr and DR-7090C

I've started to test the canon-dr backed with my DR-7090C scanner, 
with latest snapshot (libsane-canon.so.1.0.22).  I'm using xsane 
V.0.997 and scanimage V.1.0.21.

ADF Duplex and ADF Front works fine, as does all of the scanner's 
supported resolutions, and Color/Grey/Halftone/Lineart.

I'm fortunate that "ADF Front" and "ADF Duplex" is working, but 
neither xsane nor scanimage provides a "Flatbed" option.  I have 
included a list of all scanimage options detected.  There is no 
flatbed option.


==============

root at borg:/tmp# scanimage --help -d canon_dr:libusb:001:007
Usage: scanimage [OPTION]...

Start image acquisition on a scanner device and write image data to
standard output.

Parameters are separated by a blank from single-character options 
(e.g.
-d epson) and by a "=" from multi-character options (e.g. 
--device-name=epson).
-d, --device-name=DEVICE   use a given scanner device (e.g. 
hp:/dev/scanner)
    --format=pnm|tiff      file format of output file
-i, --icc-profile=PROFILE  include this ICC profile into TIFF file
-L, --list-devices         show available scanner devices
-f, --formatted-device-list=FORMAT similar to -L, but the FORMAT of 
the output
                           can be specified: %d (device name), %v 
(vendor),
                           %m (model), %t (type), %i (index number), 
and
                           %n (newline)
-b, --batch[=FORMAT]       working in batch mode, FORMAT is 
`out%d.pnm' or
                           `out%d.tif' by default depending on 
--format
    --batch-start=#        page number to start naming files with
    --batch-count=#        how many pages to scan in batch mode
    --batch-increment=#    increase page number in filename by #
    --batch-double         increment page number by two, same as
                           --batch-increment=2
    --batch-prompt         ask for pressing a key before scanning a 
page
    --accept-md5-only      only accept authorization requests using 
md5
-p, --progress             print progress messages
-n, --dont-scan            only set options, don't actually scan
-T, --test                 test backend thoroughly
-h, --help                 display this help message and exit
-v, --verbose              give even more status messages
-B, --buffer-size=#        change input buffer size (in kB, default 
32)
-V, --version              print version information
