[sane-devel] Lost support for my Canoscan N1220U

[Dave M G]

Sane Developers,

For a long while, Xsane had simply worked automagically with my Canon 
N1220U scanner.

Then, recently, I had a problem with my installed packages. Synaptic 
reported some "broken packages", and in order to fix dependency 
problems, it un-installed and re-installed a majority of the 
applications I use. At the same time, it upgraded my kernel from 2.6.17 
to 2.6.20.

After that point, Xsane no longer detected my scanner. When I opened 
Sane, it used to show me a choice between my Canon scanner and my 
Hauppauge TV input card. After the problems I had with Synaptic, Xsane 
skipped the selection screen and opened up with just the Hauppauge video 
card selected.

I figured I must have accidentally removed some necessary package, but 
after scouring the repositories for anything Sane related and installing 
them, my situation didn't improve.

So then I figured I lost some settings. I searched the Sane 
documentation, and from this web page:
http://www.sane-project.org/README.linux
... I learned of a file called /etc/ld.so.conf. After a little 
experimentation, I discovered that having the following settings in that 
file has improved the situation:

include /etc/ld.so.conf.d/*.conf
/usr/local/lib

Now, when I open Xsane, it gives me the choice between my Canon scanner 
and my Hauppauge video card.

This is better, but unfortunately, when I try to preview or acquire a 
scan, Xsane freezes and eventually just dies.

At this point I have run out ideas of  my own for how to diagnose and 
solve this problem, so I am turning here for help.

Can anyone help me identify why Xsane is no longer working as smoothly 
as it was before, and, more importantly, help me get it back to that status?

Thank you for any help or advice.
