[linux-help] Re: setup scsi scanner

[Tom Hull <thull@xxxxxxxxxxx>]

I have an Epson Perfection1640 scanner set up on a SCSI interface.
I don't exactly know the answer to your problem, nor for that matter
do I recall exactly what I did to get mine working, but let me throw
a couple of things out at you, and maybe something will click.

First thing is that getting Linux to recognize your scanner is one
thing, getting sane to recognize it is another. The Linux part is
pretty simple to check:

  cat /proc/scsi/scsi

In my case, this shows:

  Host: scsi0 Channel: 00 Id: 04 Lun: 00
    Vendor: EPSON   Model: Perfection1640  Rev: 1.03
    Type:   Processor                      ANSI SCSI revision: 02

Judging from your dmesg, you're probably OK here.

Now, in my /usr/local/etc/sane.d/epson.conf file, I have the line:

  scsi EPSON Perfection1640 Processor 0 0 4 0

You probably need something similar in your microtek.conf or microtek2.conf
file (don't know which w/o rtfm). I don't recall how sane (scanimage)
knows to use my epson.conf file, which may or may not be an important
point, but I'm pretty sure that getting a sane configuration file to
match a driver up with a scsi address is important.

There's also another whole set of nonsense involving the /dev/sg files.
I have the following symbolic links:

  /dev/scanner -> /dev/sgc
  /dev/sgc -> /dev/sg2

Once I figured out which /dev/sg file works (and note that the numbers
don't match the scsi id's; I'll also note that I've seen them move),
I can run (preferably as root, since these files aren't normally
accessible otherwise):

  scanimage -d epson:/dev/sg2

And after that scanimage --list-device seems to remember. (The
/proc/scsi/sg files may somehow tell you what the mapping is, but
offhand I can't tell you how.) Once you know which /dev/sg# file
works, symlink /dev/scanner to it. (I have no idea what /dev/sgc
is doing here.) Also chmod a+rw the file.

Also, I've managed to lose some/all of these settings when new
software is installed, and there may be gremlins going around and
tightening up file permissions, which causes scanimage --list-device
to fail without a helpful error message.

Also, in my case I built sane/xsane from scratch, and patched in an
even later device driver (thanx to a guy in Germany), since my
machine was on the bleeding edge of almost-supported (bled about
every third scanline, in fact). Your milleage may vary.
