[sane-devel] CanoScan N650U (plustek backend) not working with Mac OS X 10.3.2 build 7D24

[Henrik Rintala]

I do not seem to get the CanoScan N650U to work with my installation. I 
first tried it with the precompiled
software from <http://www.ellert.se/twain-sane/> and after I could not 
get it to work, I downloaded additionally
<http://www.sane-project.org/snapshots/sane-backends-2003-12-23.tar.gz> 
and compiled it.

With both versions the problem is that scanimage does not seem to be 
able to connect to the scanner.

Before compiling the latter packet I also tried editing the 
plustek.conf file without success (setting the vendor and product id).

Maybe someone has an idea what to try next.

Thanks!

Below you will see the results of the following commands:
- sane-find-scanner
- scanimage -L
- sane-find-scanner -v -v

Here is what I get:

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).
