[sane-devel] Xerox Travel Scanner 100 could not be detected

Hello
I am trying to make Xerox Travel Scanner 100 portable scanner under
Ubunto 9.10(karmic).
When I use sane-find-scanner -v -v, it shows:

found USB scanner (vendor=0x04a7 [Xerox], product=0x04ac [Travel Scanner
100], chip=GL841) at libusb:001:003

But when I try to use scanimage -L it show only my webcam device and no
scanner :
scanimage -L
WARNING: Unhandled message:
interface=org.freedesktop.DBus.Introspectable, path=/, member=Introspect
device `v4l:/dev/video0' is a Noname CKF7037 virtual device

I have tried to modify GL841 chip configuration file (genesys.conf) with
the following string :

# Xerox Travel Scanner 100
usb 0x04a7 0x04ac

but it did not give any positive result. 
Please advice what should I do more to make this wonderful device
working.
Thanks in advance.
