I tell my kernel that the scanner is connected using:
echo "scsi add-single-device 0 0 6 0" > /proc/scsi/scsi

I tell my kernel that the scanner is disconnected using:
echo "scsi remove-single-device 0 0 6 0" > /proc/scsi/scsi

I'm not sure that you can connect a different type of scanner. I'm
also not sure about hot-plugging SCSI. YMMV....
