[sane-devel] trying to get a Benq4300U USB scanner working .....

Dear sane people,
I have tried to get my scanner to work a number of times under
Fedora Core 6 on my machine (1200 MHz Athlon) but have not
succeeded.
I am now trying with Debian on the same machine on a second drive.
It is pretty recalcitrant and it may still not work but I will post
some of my efforts here and if you would make suggestions I would be
grateful.
What is REALLY sad is that if I can't succeed I will have to wipe
Fedora off and reinstall Windows 98 just so I can scan images.
Yikes....
The other alternative is to go to the library and use the scanner
there. I would still be using Windows but at least not on my own
machine.
OK. Here goes.
As you can see I have edited the snapscan.conf file that lives in
/etc/sane.d and bunged in the driver for the scanner I use and the
device directory /dev/usb/scanner0.

No scanners were identified. If you were expecting something
different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the
documentation
which came with this software (README, FAQ, manpages).

OK, let's rock the joint and run cat /proc/bus/usb/devices:

P.S. I tried Vuescan linux version and it worked immediately. But it is
proprietary software.....
