send the files to me. You are right, more than 400 kB a bit too much for
the list. (compressing them with gzip might shrink them considerably,
Regarding the contents, I expect to get at first an idea, if your
problem is related to the backend (about which I don't know very much),
or if it is related to the SCSI stuff in Sane (sanei_scsi library, about
which I know a bit more) or to the Linux SCSI system (about which I
don't know very much).
