Not a issue in 13.04
Also 10.0.0.50 is running 13.04
This does not have a 100% reproduction rate, sometimes it hangs indefinitely and some times it works
Terminal output, last 6 lines matter, the rest proves it should work

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
-A, --all-options list all available backend options
-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
Options specific to device `net:10.0.0.50:plustek:libusb:004:002':
Scan Mode:
--mode Lineart|Gray|Color [Color]
Selects the scan mode (e.g., lineart, monochrome, or color).
--depth 8|14bit [8]
Number of bits per sample, typical values are 1 for "line-art" and 8
for multibit scans.
--source Normal|Transparency|Negative [inactive]
Selects the scan source (such as a document-feeder).
--resolution 50..1200dpi [50]
Sets the resolution of the scanned image.
--preview[=(yes|no)] [no]
Request a preview-quality scan.
Geometry:
-l 0..215mm [0]
Top-left x position of scan area.
-t 0..297mm [0]
Top-left y position of scan area.
-x 0..215mm [103]
Width of scan-area.
-y 0..297mm [76.21]

--contrast -100..100% (in steps of 1) [0]
Controls the contrast 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,... [inactive]
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).
--red-gamma-table 0..255,... [inactive]
Gamma-correction table for the red band.

--warmup-time -1..999 (in steps of 1) [-1]
Warmup-time in seconds.
--lamp-off-during-dcal[=(yes|no)] [inactive]
Always switches lamp off when doing dark calibration.
--calibration-cache[=(yes|no)] [no]
Enables or disables calibration data cache.
--speedup-switch[=(yes|no)] [yes]
Enables or disables speeding up sensor movement.
--calibrate [inactive]
Performs calibration
