[sane-devel] Vuego 610s / 310s (?) summary.

Thanks all for your help with my Vuego 610 scanner problem. I've done a 
write-up for the ones that come after me. Please correct any obvious 
mistakes.

Installing a Vuego 610s scanner under Mandrake Linux 9.0

The short answer:

A typo in the SANE configuration files on Mandrake causes the device 
only to be recognized if explicitly specified. e.g. "scanimage -d 
/dev/sg0" will work but "xsane" will give a "No devices found" error. 
Check /etc/sane.d/dll.conf and replace all occurences of "SnapScan" 
with "snapscan". If "/etc/sane.d/SnapScan.conf" exists it can safely be 
deleted/moved out of the way. I also had to uncomment all references to 
usb devices in /etc/sane.d/snapscan.conf.

More details:

In the process of moving my girlfriend from Win98 to Mandrake 9.0 I had 
to get her Vuego 610s SCSI scanner working, preferably under KDE.

First of all, make sure you SCSI card (Adaptec 2906, using aic7xxx 
driver) is recognized by the system. Check if /proc/scsi lists your 
card, in my case /proc/scsi/aic7xxx.

Control the hardware: is the scsi bus correctly terminated, scanner 
properly connected to SCSI interface, was the scanner powered on during 
boot? Vuego 610 scanners seem to require termination in Linux though 
this is NOT the case in Windows.

Check if your scanner is properly recognized by the system. "cat 
/proc/scsi/scsi" should list entries for all SCSI devices on the bus. I 
found two devices: my CD-RW and 'Flatbedscanner_4'. Bingo! If the 
scanner is not found, try reloading the scsi modules and disabling the 
ide-scsi module if you have a CD-R/RW. Removing modules: "rmmod 
aic7xxx; rmmod sg; rmmod ide-scsi". Reloading aic7xxx module only: 
"modprobe sg; modprobe aic7xxx". "cat /proc/scsi/scsi" again. If the 
scanner still isn't found, you may have a kernel problem.

Next, you need to modify you "/etc/sane.d/snapscan.conf" file. I had to 
remove all references to usb and uncomment the line where my scsi 
device is defined. I also removed the "firmware" line because I didn't 
see the point in keeping it. Thus, I have only one line reading 
"/dev/sg0", everything else is commented out. If you have a 
"/etc/sane.d/SnapScan.conf" file you can safely delete it. It's a crud 
Harddrake probably spit out and doesn't do anything anyway.

By now, you should be able to perform scans from the command-line by 
explicitly specifying the SANE backend you want to use, like this: 
"scanimage --device-name=snapscan:/dev/sg0 > outputfile.ppm".

The same typo in the SnapScan.conf file shows up in 
"/etc/sane.d/dll.conf". Replace all occurences of "Snapscan" with 
"snapscan" and you should be able to scan without explicitly specifying 
the device name: xsane works!

Cheers & Thanks for your help.
