I am sorry for the problem, but it appears that the introduction of focus controls for the Canon FS2710 somehow disrupted the focus controls for the FS2700. Unfortunately, I do not have an FS2700, and so I cannot test the backend for this scanner.
If you say that sane version 1.0.13 worked for you, this gives me a clue where to start hunting for the bug. But please don't expect a quick answer. As a workaround you can copy the relevant files (canon.c, canon-sane.c, canon-scsi.c, canon.h) from the 1.0.13 version to your actual backend directory and recompile. That should help, provided that the bug is where we think it is. Best regards, Ulrich Deiters
