Hi,
scanimage seg faults every time when using the --help -d options. I am
attaching the output. If you need more information please let me know.
Thanks,

Usage: scanimage [OPTION]...
Start image acquisition on a scanner device and write PNM image data to
standard output.
-b, --batch=FORMAT working in batch mode
-d, --device-name=DEVICE use a given scanner device
-h, --help display this help message and exit
-L, --list-devices show available scanner devices
-T, --test test backend thoroughly
-v, --verbose give even more status messages
-V, --version print version information
Options specific to device `net:octopus:hp:/dev/sgb':
Scan Mode:
--preview[=(yes|no)] [no]
Request a preview-quality scan.
--mode Lineart|Grayscale|Color [Color]
Selects the scan mode (e.g., lineart,monochrome, or color).
--resolution 300..2400dpi (in steps of 300) [300]
Sets the resolution of the scanned image.
Enhancement:
--brightness -127..127 (in steps of 1) [0]
Controls the brightness of the acquired image.
--contrast -127..127 (in steps of 1) [0]
Controls the contrast of the acquired image.
Advanced Options:
--custom-gamma[=(yes|no)] [no]
Determines whether a builtin or a custom gamma-table should be
used.
--gamma-table 0..255,... (in steps of 1.52588e-05)
Gamma-correction table. In color mode this option equally
affects the
red, green, and blue channels simultaneously (i.e., it is an
intensity
gamma table).
--matrix-type Auto|NTSC RGB|Pass-through [NTSC RGB]
Set the scanners color matrix.
--matrix-rgb -1.98438..1.98438,... (in steps of 1.52588e-05)
Custom color matrix.
--speed Slow|Normal [Normal]
Determines the speed at which the scan proceeds.
--smoothing Auto|Off|2-pixel|4-pixel|8-pixel [Auto]
Select smoothing filter.
--media-type Print|Slide|Film-strip [Film-strip]
Set type of media.
--ps-exposure-time
Default|125%|150%|175%|200%|225%|250%|275%|300%|Negative [Default]
A longer exposure time lets the scanner collect more light.
Suggested
use is 175% for prints, 150% for normal slides and "Negatives"
for
negative film. For dark (underexposed) images you can increase
this
value.
--depth 8|10 [8]
Number of bits per sample, typical values are 1 for "line-art"
and 8
for multibit scans.
--unload-after-scan[=(yes|no)] [no]
Unloads the media after a scan.
