Canon FS4000 support

I once had an opportunity to look at an SCSI protocol of
a FS4000. The protocol differs significantly from those
of the SCSI flatbed scanners and the older film scanners.
Moreover, there appear several SCSI commands which my
handbook lists as "proprietary/undocumented". Reverse
engineering will therefore require much experimental
work.

And who knows - perhaps Canon built some unconventional
commands into the scanner ("eject light bulb", "burn
the slide") to discourage people like us? :-)

Regards,

Ulrich Deiters

HP5370C still not working

Hello.

In January, I reported that the HP5370C, supported by the 
"avision" back-end, was not behaving correctly (producing
an image skewed by a 45 degree angle).

I retried yesterday, and to my deep disappointment, the scanner
doesn't even go that far anymore: trying

 scanimage -d avision:libusb:002:007 > image.pnm

the scanner tray moves a little (but in the wrong direction),
and after some 3 seconds, the light starts flashing.

Best regards,
Gilles

P.S. Rene Rebe answered my previous post by offering to test
     newer, but I must have overlooked his mail at the time;
     sorry for that.
     Anyway, I've upgraded since then:

     Debian GNU/Linux 2.6.5
     scanimage (sane-backends) 1.0.14; backend version 1.0.14
     libusb-0.1-4
     udev O.024

There have been reports about USB trouble with Linux 2.6.5 and 2.6.6.
I don't know if that's valid for all USB scanners. As far as I can see
the reports are mostly about Epson scanners.
Nevertheless, have a look at syslog and check for bulk timeouts/errors.

I'm using Linux 2.6.7-rc2 and don't see any USB errors but I'm using
Mustek and Plustek scanners only and haven't tested 2.6.5 or 2.6.6.

Bye,
  Henning

RE: JSane

Rainer,

If there is any type of java scanning API, let Andi and I know. We aren't aware of any. I have been trying to use
the existing japi classes for some time now, and they are kind of broken. Andi's classes look
interresting, and I would like to try them soon (if I can ever get a saned damon running).

Oh. I never heared of s.th. like that.

If it is ok for you I schedule a review of your logs for the weekend -
I have two very important other things to do first ...

Thanks for this hints Henning. Gilles, could you check if you hit this
USB errors?

Re: HP5370C still not working

I'm not sure how much of this can be laid at the door of "USB", I think it  
is more specifically trouble with SANE backends.

I had wasted probably weeks trying to get my cannon FB630U to work under  
2.6x kernels until some helpful sole suggested I try vuescan.

This worked beautifully straight out of the box and produces better  
results that I had got with the sane backend when it did work under 2.4

I would like to work with open source solutions but there is a limit to  
how much time I can reasonably spend on a broken driver (and I have  
already over-stepped that mark by an order of magnitude. ) Emails to the  
maintainer remain unanswered.

Big thanks to the guy who made me aware of vuescan.

Regards to all.

If several sane backends fail with two specific kernel versions and
those backends worked with older kernel versions then the conclusion
that it might be a kernel issue isn't far-fetched.

If you have facts that there is a bug in the backends that only
showed up because of kernel changes, please tell us.

Just to make one point clear: There is no general problem with SANE
concerning Linux 2.6.

Can someone else confirm that the canon630u backend does not work on
Linux 2.6? So we can either add a warning about trouble with Linux 2.6
for this scanner?

I'm sorry for that. Could you please send a summary of the problems
and possible solutions/work-arounds you have found until now? Or if
you have already done that, could you point me to that posting? This

When the command

  SANE_DEBUG_AVISION=7 scanimage -d avision:libusb:001:002 -l 5mm -t 5mm -x 15mm -y 15mm

was run, here is the result from "tail -f kern.log" (so, the lines corresponding 
to the "scanimage" itself start at "Jun  1 17:49:11"):

That was a bug in the fujitsu backend. I've fixed that, checkout the
latest version.
