Xsane problem

Hello, I'm using Ubuntu 9.04. i have connected a scanner, Mustec BearPaw 1200cs [which is supportd by Sane]
when i press Applications>Graphics>Xsane image scanning program, i get an error message: Failed to open device 'gtk68xx:libusb:004:002': Invalid argument . it is not a problem regarding permissions because when i type in the Terminal with sudo i get the same message, it seems that it is related to backend problems. the version i have installed is :xsane-0.996
Thanks for any help

Did you get the backend file and add it to the Sane install, as instructed on the Sane website?

If your scanner is not working right away, then follow these guidelines (from
There are two ways to get an up-to-date Mustek SCSI backend from this site: Use a current snapshot or the backend itsself. The CVS snapshots contain the complete SANE distribution and are rather big. If you don't have the latest SANE source code installed, it's probably best to start with a snapshot. Otherwise the backend alone will be ok.
You can also access the official SANE CVS tree, it contains the latest mustek backend.
I'm not sure if this is not rather a problem with your USB device configuration. Does every other USB device (like headphone, etc) work correctly?

Thanks, It turned out that i had to download the firmware from:
and place it in /usr/share/sane/gt68xx. afterwards i tried to scan, Xsane opened up, did a scan, but the scan came out blurred in a way, not clear, perhaps it is just a matter of configuring it? i don't know. perhaps i should update the software to a later version? [as i mentioned above, mine is version xsane-0.996]
is there a download for Debian/Ubuntu?
Thanks for any help
