¿Como configuro scanner primascan colorado 2400 u?

Hola a todos. Estoy intentado configurar un scanner primascan colorado 2400 u en mi laptop. (que tiene 2009.1)
cuando corro el sane solo me detecta la webcam. por consola si encuentra es scanner como verán:

sane-find-scanner

# sane-find-scanner will now attempt to detect your scanner. If the
# result is different from what you expected, first make sure your
# scanner is powered up and properly connected to your computer.

# No SCSI scanners found. If you expected something different, make sure that
# you have loaded a kernel SCSI driver for your SCSI adapter.

found USB scanner (vendor=0x0461 [Primax], product=0x0346 [USB Scanner]) at libusb:004:004
# Your USB scanner was (probably) detected. It may or may not be supported by
# SANE. Try scanimage -L and read the backend's manpage.

# Not checking for parallel port scanners.

# Most Scanners connected to the parallel port or other proprietary ports
# can't be detected by this program.

# You may want to run this program as root to find all devices. Once you
# found the scanner devices, be sure to adjust access permissions as
# necessary.

Luego le doy el scanimage -L y esto es lo que me sale:
device `v4l:/dev/video0' is a Noname Laptop Integrated Webcam virtual device

No sé donde le creo un vínculo para que encuentre el scanner. ¿Alguna idea?
gracias
