plustek: Thread: Fedora and CanoScan N 650U

Hi,
  I hope someone can answer my questions.  I have been using my CanoScan 
N 650U scanner with Linux using the plustek module long before it was 
even working correctly.  I believe it was with RH 8.0 that I first got 
it working correctly by compiling the most recent Sane and Plustek from 
source.  I was so happy that it finally worked great and no longer has 
to switch to MS Win to use my scanner.  When I switched to Fedora Core 1 
I was pleased that my scanner worked out of the box without having to do 
any configuration.  Unfortunately though when I updated the Sane 
packages latter on the quality of the scanned images became virtually 
unusable again.   I tried changing various setting but was never able to 
get an usable picture.  I hoped that when I upgraded to Fedora core 2 
that it would work again but unfortunately it is the  same.  Fedora Core 
1 came with Sane-backends 1.0.12-4, I am not sure what the upgrade 
package version that broke it was.  Fedora Core 2 comes with  1.0.13-7. 

So for the questions, Is this a known problem with this scanner?  If so, 
is there a fix?  If not, is it possible to use the older sane, 1.0.12 
with the 2.6 kernel?  Any other suggestions?

Thanks

The SANE versions in general do not rely on a specific kernel.
You can use 1.0.12 on kernel 2.6 you have to make sure, that
the libusb is installed.
It might be, that the kernel you use has USB problems, this seems
to be quite common for the 2.6 series...
What are exactly your problems?

Ciao,
