The long time looks like there are SCSI-related problems. What about
"cat /proc/scsi/scsi"? Maybe you can check termination, cables etc.
The two entries are ok, usually /dev/sga is a link to /dev/sg0.

With "sane-find-scanner -v" you can check at which point the long
waiting time occurs.

This also looks like SCSI-problems. I don't think it's related to
xsane or SANE in general. Are there other devices on this SCSI bus?
