device `canon:/dev/sg1' is a CANON IX-06015C        flatbed scanner

This seems OK to me - the scanner is recognised by sane, and there are no 
error messages.

Yes, /dev/sg1 and /dev/scanner are in canon.conf and I have made links 
between the two. I also have /dev/sg1 and /usr/bin/xsane in 
/etc/sane.d/snapscan.conf.

Everything seems ready to go, but it doesn't. I'm puzzled. Any help or 
suggestions much appreciated.

Thanks again,
Barry
