Dear Thomas,
Could your canoscan2700F work well on Windows machine?

Well, could your Linux PC find the scanner?
Could you find your scanner by following command?

# cat /proc/scsi/scsi

And could you find your scanner by following command?

# cd /sane-backend-1.0.14/tools/
# ./sane-find-scanner

Or

# scanimage -L

why I have also problems with backend 1.0.13 and 1.0.12?

First I modified the original canon-backend for canoscan2700F to use my
canoscanFB620S.
And Ulrich modified the canon-backend I had modified to use his
canoscanFS2710.
And the canon-backend was introduced to sane1.0.12, 1.0.13, 1.0.14....
So, if I changed the code for canoscan2700F in the original canon-backend,
the change may be a cause of this problem.
Therefore, if you have also problems with backend 1.0.13 and 1.0.12, check
of  the original canon-backend for canoscan2700F is useful I think...
But, before your PC worked well with 2700F using sane1.0.13, isn't it?
And about your problem with xsane0.91, Oliver Rauch said as follows;

Could the newest version of xsane solve the problem?

I think the last problem that all version of sane cannot work is an another
problem....

Ok, sane developers are great, so, your debug output will be helpful.
