Looks like you try to scan from the CD (/dev/sg0) :-)

Did you reboot? Then your scanner will be /dev/sg0 after the reboot.
That's why it is detected mow:

The snapscan backend only looks for the device mentioned in
snapscan.conf. I don't know if this is supported by this backend but
you could try to add both devices to snapscan.conf. Or use something
like "scsi AGFA" in snapscan.conf.
