I AM USING THE FOLLOWING CONF FILE
plustek.conf with the following settings....

# Plustek-SANE Backend configuration file
# For use with Plustek parallel-port scanners and
# LM9831/2/3 based USB scanners
#
# For parport devices use the parport section
#
#[parport]
#device /dev/pt_drv

#
# leave the default values as specified in 
etc/modules.conf
#
option warmup    -1
option lOffOnEnd -1
option lampOff   -1

#
# The USB section:
# each device needs at least two lines:
# - [usb] vendor-ID and product-ID
# - device devicename
# i.e. for Plustek (0x07B3) UT12/16/24 (0x0017)
[usb] 0x04a9 0x220d
device /dev/usbscanner2
#
# additionally you can specify some options
# warmup, lOffOnEnd, lampOff
#
# For autodetection use
# [usb]
# device /dev/usbscanner
#
# NOTE: autodetection is safe, as it uses the info it
got
#       from the USB subsystem. If you're not using
the
#       autodetection, you MUST have attached that
device
#       at your USB-port, that you have specified...
#

#[usb]

#
# options for the previous USB entry
#
# switch lamp off after xxx secs, 0 disables the
feature
option lampOff 0

# warmup period in seconds, 0 means no warmup
option warmup 30

# 0 means leave lamp-status untouched, not 0 means
switch off
# on sane_close
option lOffOnEnd 0

#
# options to tweak the image start-position
# (WARNING: there's no internal range check!!!)
#
# for the normal scan area
#
option posOffX 0
option posOffY 0

# for transparencies
option tpaOffX 0
option tpaOffY 0

# for negatives
option negOffX 0
option negOffY 0

#
# for setting the calibration strip position
# (WARNING: there's no internal range check!!!)
# -1 means use built in
#
option posShadingY -1
option tpaShadingY -1
option negShadingY -1

#
# to invert the negatives, 0 disables the feature
#
option invertNegatives 0

# for skipping calibration step
option skipCalibration 0

# for replacing the gain values found during
# calibration
option red_gain   -1
option green_gain -1
option blue_gain  -1

#
# for adjusting the default gamma values
# use values of 2.5 for CanoScan
#
option redGamma         1.0
option greenGamma       1.0
option blueGamma        1.0
option grayGamma        1.0

#
# to enable TPA (non Plustek devices only)
# 0 means default behaviour as specified in the
internal tables
# 1 means enable
#
option enableTPA 0

#
# and of course the device-name
#
device /dev/usbscanner2

#
# to define a new device, start with a new section:
# [usb] or [parport]
#

NOW, what am i doing wrong?
i have gone through many readme and install files.

i guess that i may have over looked something.

thanks
