Hi Dep

Try grabbing the firmware binary from the windows drivers and have it load 
when you call the scanner.

You will have to check out some howtos to get it right. 
This is assuming it's a firmware loading problem like mine was.

Find the conf file for your scanner and add something like

# Path to the firmware file
# This file comes with the Windows driver
# The scanner won't work without it
option artecFirmwareFile /usr/share/sane/artec_eplus48u/Artec48.usb
