"Failed to start scanner: Unknown SANE status code -1."

Stops in the same place it always has.  I am wondering if the Umax
Vista-S6E SCSI scanner works with any recent version of SANE or if I
have a really, really version of that model.

MacOS 10.2.8.  Debugging log attached.

The code is already there for OS/2--I removed the conditional.  But it
still fails in the same way--stops a bit of the way into a preview
scan with a timeout.

Changes and log attached.  I wonder if this version would work on
Linux.

No answer on this one.

So, then.  Let's try narrowing this down.  Does anyone have a Umax
Vista-S6E working with SANE on any version of Mac OS 10.2?

uname -r will give that; but thinking it over, it might be better to
test for the old API by checking for the IOKit/IOCFPlugIn.h header,
and test for the new one by checking for
IOKit/scsi-commands/SCSICmds_INQUIRY_Definitions.h.

Darwin version 6 or higher, I think, would work.

I think, probably, a better approach would be to have sanei_osx_SAM.c.
But, the API is very new, and Apple plans on offering their own
standard scanner driver ("In later versions of Mac OS X, however, the
mass storage stack will include support for other SCSI peripheral
devices, such as scanners."), so it may be best to wait on that.

Meantime, I tried removing fork() from the SCSI driver on OS X (the
job has already been done for OS/2, so it was simple) and I still have
my scanner problem.  Bah!

Would that this was that simple!  The new Mac OS X "SCSI Architecture
Model" is misnamed; it is a grand unified transport layer, covering
"SCSI, USB (Storage), FireWire SBP2 and ATAPI".  So this may be the
story for a lot of different scanners in 10.3 and later versions of Mac
OS.  Or maybe not, depending on how many manufacturers adopt it.

Perhaps it would be a good idea to start a
sanei_osx_scsi_architecture_family file?

The Mac OS X SCSI drivers are a work in progress.  Take a look at

for details.

[sane-devel] SANE, Darwin, Umax Vista-S6E problems

2003-11-03 Thread Randolph Fritz 
The scanner works fine with the demo version of Vuescan, and the Zip
drive on the SCSI chain also works fine.  When I run xsane and try to do =
a
preview, the scanner starts, then stops, and after a pause I get the
following error pop-up:
  Failed to start scanner: Unknown SANE status code -1

Versions:

  Umax Vista-S6E 1.7
  Mac OS X 10.2.8 (6R73)
  Darwin Kernel Version 6.8: Wed Sep 10 15:20:55 PDT 2003;

  sane-backends  1.0.12-2
  sane-backends-shlibs  1.0.12-2
  xsane 0.89-2
  fink  0.13.2-1

By the way, is there any way to change xsane's default doc viewer?  I hav=

Camino, not Netscape.
