I wrote this udev rule to create /dev/scanner:
SUBSYSTEMS=="scsi", SYSFS{vendor}=="SCANNER ", OWNER="saned", GROUP="jplatte", 
MODE="660", NAME="scanner"

root at jako:~> ls -la /dev/scanner
crw-rw---- 1 saned jplatte 254, 5 2007-10-03 14:37 /dev/scanner

No.

Here it is:
root at jako:~> SANE_DEBUG_SANEI_SCSI=255  sane-find-scanner

  # sane-find-scanner will now attempt to detect your scanner. If the
  # result is different from what you expected, first make sure your
  # scanner is powered up and properly connected to your computer.

An old Symbios based card
02:07.0 SCSI storage controller: LSI Logic / Symbios Logic 53c875 (rev 26)

with this driver:
sym53c8xx              66964  0
scsi_transport_spi     20864  1 sym53c8xx
scsi_mod              122124  8 
sg,sr_mod,st,sd_mod,osst,sym53c8xx,scsi_transport_spi,libata

After some reboots I discovered, that the scanner is recognized by 
sane-add-scanner if it is turned on during system boot. It is not detected 
after executing the following script to rescan all SCSI busses (I'm using 
ata_piix, hence there is more than one SCSI bus):
for device in /sys/class/scsi_host/host*/scan ; do
        echo "0 - -" > $device
done
With this script the kernel detects the scanner according to /proc/scsi/scsi 
and the device node is created:
Host: scsi0 Channel: 00 Id: 06 Lun: 00
  Vendor: SCANNER  Model:                  Rev: 2.02
  Type:   Scanner                          ANSI  SCSI revision: 01 CCS

but then sane-add-scanner is not able to find it. Looks more like a kernel 
bug, because this script worked fine with older kernels.

regards,
Jörg
