[sane-devel] sane nikon coolscan

[Hidong Kim]

Hi,

I'm trying to install a Nikon Coolscan LS-2000 on my Red Hat 7.1 
machine.  I recompiled the 2.4.2-2 kernel to support the SCSI interface 
for this scanner, an Adaptec AVA-2903B.  (It uses the aic7xxx driver.)  
The computer appears to recognize the SCSI host and the scanner fine.  
Here are some lines from /var/log/messages during boot:

Oct 13 23:25:16 driver kernel: scsi0 : Adaptec AIC7XXX EISA/VLB/PCI 
SCSI HBA DRIVER, Rev 6.1.7

Here's 'cat /proc/scsi/scsi':

I downloaded and installed sane 1.0.5 backends and frontends.  I didn't 
see any errors during the installation.  The scanimage and xscanimage 
executables were created.  But sane does not detect any scanners.  
Here's the output of 'scanimage --list-devices':

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).


Here's the output of  'tools/sane-find-scanner':

# Note that sane-find-scanner will find any scanner that is connected
# to a SCSI bus.  It will even find scanners that are not supported
# at all by SANE. It won't find a scanner that is connected to a
# parallel, USB or other non-SCSI port.

# If your scanner uses SCSI, you must have a driver for your SCSI
# adaptor and support for SCSI Generic (sg) in your Operating System
# in order for the scanner to be used with SANE. If your scanner is
# NOT listed above, check that you have installed the drivers.


The scanner is turned on and connected.  Why is sane not detecting the 
scanner when the computer seems to be detecting it?  What else can I 
check?  Thanks,
