I tried that command here.
It didn't like the sequence (I think the -h is a little off).


this is the output I got....

*********************************************************
Usage: scanimage [OPTION]...

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

- -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), and %i (index number)
- -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 number in filename by an amount of #
    --batch-double         increment page number by two for 2sided originals
                           being scanned in a single sided scanner
    --accept-md5-only      only accept authorization requests using md5
- -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
- -V, --version              print version information

Options specific to device `mustek:/dev/sg0':
  Scan Mode:
    --mode Lineart|Halftone|Gray|Color [Gray]
        Selects the scan mode (e.g., lineart,monochrome, or color).
    --fast-gray-mode[=(yes|no)] [inactive]
        Scan in fast gray mode (lower quality).
    --resolution 72..600dpi (in steps of 1) [72]
        Sets the resolution of the scanned image.
    --depth 8|12 [inactive]
        Number of bits per sample, typical values are 1 for "line-art" and 8
        for multibit scans.
    --speed Slowest|Slower|Normal|Faster|Fastest [inactive]
        Determines the speed at which the scan proceeds.
    --source Flatbed [inactive]
        Selects the scan source (such as a document-feeder).
    --preview[=(yes|no)] [no]
        Request a preview-quality scan.
    --fast-preview[=(yes|no)] [no]
        Request that all previews are done in in the fastest (low-quality)
        mode. This may be a non-color mode or a low resolution mode.
  Geometry:
    -l 0..218mm [0]
        Top-left x position of scan area.
    -t 0..293mm [0]
        Top-left y position of scan area.
    -x 0..218mm [218]
        Width of scan-area.
    -y 0..293mm [293]
        Height of scan-area.
  Enhancement:
    --brightness -100..100% (in steps of 1) [0]
        Controls the brightness of the acquired image.
    --brightness-r -100..100% (in steps of 1) [inactive]
        Controls the brightness of the red channel of the acquired image.
    --brightness-g -100..100% (in steps of 1) [inactive]
        Controls the brightness of the green channel of the acquired image.
    --brightness-b -100..100% (in steps of 1) [inactive]
        Controls the brightness of the blue channel of the acquired image.
    --contrast -100..100% (in steps of 1) [inactive]
        Controls the contrast of the acquired image.
    --contrast-r -100..100% (in steps of 1) [inactive]
        Controls the contrast of the red channel of the acquired image.
    --contrast-g -100..100% (in steps of 1) [inactive]

    --contrast-b -100..100% (in steps of 1) [inactive]
        Controls the contrast of the blue channel of the acquired image.
    --custom-gamma[=(yes|no)] [no]
        Determines whether a builtin or a custom gamma-table should be used.
    --gamma-table 0..255,...
        Gamma-correction table.  In color mode this option equally affects the
