Upgraded to Ubuntu 12.04.  And was using gscan2pdf when I realized that I
could not scan in any other mode than color.  Previous version, 10.04
Ubuntu, I could scan in all three modes, color, line art & gray scale.
 This does not appear to be the case with the sane-backend 1.0.22

Options specific to device `avision:libusb:001:005':
  Scan mode:
    --mode Color [Color]
        Selects the scan mode (e.g., lineart, monochrome, or color).
    --resolution 50..600dpi (in steps of 1) [150]
        Sets the resolution of the scanned image.
    --speed 0..4 (in steps of 1) [inactive]
        Determines the speed at which the scan proceeds.
    --preview[=(yes|no)] [no]
        Request a preview-quality scan.
    --source ADF Front|ADF Back|ADF Duplex [ADF Front]
        Selects the scan source (such as a document-feeder).
    -l 0..216mm [0]
        Top-left x position of scan area.
    -t 0..362mm [0]
        Top-left y position of scan area.
    -x 0..216mm [216]
        Width of scan-area.
    -y 0..362mm [362]
        Height of scan-area.
    --overscan-top 0..4mm [inactive]
        The top overscan controls the additional area to scan before the
        is detected.
    --overscan-bottom 0..4mm [inactive]
        The bottom overscan controls the additional area to scan after the
        paper end is detected.
    --background-lines 0..50pel [inactive]
        The background raster controls the additional background lines to
        before the paper is feed through the scanner.
    --brightness -100..100% (in steps of 1) [0]
        Controls the brightness of the acquired image.
    --contrast -100..100% (in steps of 1) [0]
        Controls the contrast of the acquired image.
    --quality-scan[=(yes|no)] [yes]
        Turn on quality scanning (slower but better).
    --quality-cal[=(yes|no)] [yes]
        Do a quality white-calibration
    --gamma-table 0..255,... [inactive]
        Gamma-correction table.  In color mode this option equally affects
        red, green, and blue channels simultaneously (i.e., it is an
        gamma table).
    --red-gamma-table 0..255,...
        Gamma-correction table for the red band.
    --green-gamma-table 0..255,...
        Gamma-correction table for the green band.
    --blue-gamma-table 0..255,...
        Gamma-correction table for the blue band.
    --exposure 0..1000% (in steps of 1) [inactive]
        Manual exposure adjustment.
    --infra-red[=(yes|no)] [inactive]
        Enable infra-red scan mode.
    --multi-sample[=(yes|no)] [inactive]
        Enable multi-sample scan mode.
  Scan mode:
    --frame 0..0 [inactive]
        Selects the number of the frame to scan
    --power-save-time <int> [15]
        Allows control of the scanner's power save timer, dimming or turning
        off the light.
    --paper-length[=(yes|no)] [no]
        Newer scanners can utilize this paper length to detect double
        However some others (DM152) can get confused during media flush if
        is set.
    --flip-page[=(auto|yes|no)] [inactive]
        Tells page-flipping document scanners to flip the paper back to its
        original orientation before dropping it in the output tray.  Turning
        this off might make scanning a little faster if you don't care about
        manually flipping the pages afterwards.

Type ``scanimage --help -d DEVICE'' to get list of all options for DEVICE.

Any help would be appreciated and would prefer to use the latest version.
