I got it working, I'm going to have to apply the patches every time sane
rebuilds, but it works!

Sorry for not getting back, I could not get the package manager
(portage), to accept that I would build the package.
I ended up creating en ebuild file and manually inserted it into
the package repository, which is hackish, but it works.

I looked at your patches and they seem quite clean.
Sadly, my scanner still does not work, but I think that the reasons are
unrelated. I'm inserting some of the debug info below.
If it makes any difference, my scanner's light was on.

Thanks,
David

OK, I did this:
BACKENDS="avision" ./configure --without-api-spec

Compile and install went through.

Then I got:

BACKENDS="avision" ./configure --without-api-spec

So I'm not certain whether the compiling process was successful in the
end. 

The first SANE_USB_WORKAROUND=1 scanimage -L was successful, a second
try did not deliver any results.

Debugging attempt delivers as follows.
Hope that says something.

That's where the build is converting the SANE API specification to
PostScript and/or PDF.  It's bombing because it cannot find the desired
font files.

If you just want to use your scanner (as opposed to writing a SANE
backend or frontend), you don't need the spec.

You have two options:

 1) run ./configure --without-api-spec
 2) install the texlive-fonts-recommended package (and maybe other
texlive-fonts-* packages)

If I were you, I'd go with 1).

Hope this helps,

Thanks (got your cc'ed patches), I had been planning to create a patch
myself either next week or the following. In lieu of that I will look at
yours.
I know how to write C but am not familiar with the sane or any other
deice controlling code, so I will need to get up to speed (and put my
other projects aside :) . Please don't be surprised if you do not hear
from me soon, I tend to be a slow learner and fairly methodical when
coding or reading code.

Thanks,
David

I don't have any USB3 hardware in my machines, and the xhci module is
not involved.
Anyway, I can give it a try.

Shall i try this version: http://www.sane-project.org/snapshots/sane-ba

And are these instructions o.k. ?

This sounds like the typical linux usb3 problems. If you use a
sane-backends git snapshot, the problem may go away. If not, that
version also has another option: you can try to invoke your scanning
program with an additional env var: SANE_USB_WORKAROUND=1

Hello Dave,

great you're taking care for me.
A few days ago I filed a bug report which contains most of your
requested info:

https://bugs.launchpad.net/bugs/1643544

The test you asked for have already been carried out:

On my laptop, running ubuntu 16.04, the problem occurs as well.
And: On my desktop, with fedora 24 - the problem ALSO EXISTS

With a debian 8.6, kernel 3.2 (or so), booted for an external USB hdd -
NO PROBLEM AT ALL. Multiple pages, high resolutions - everything fine. 

My conclusions from these experiments:

* scanner is o.k.
* desktop  is o.k.
* kernel 4.X causes problems, distro-independently

Let me know if I can provide further information.

Hi, Wolf!  I read through your messages and glanced at the logs.  If I
understand correctly, your situation seems to be a "nothing much had
changed, but it no longer works" problem?

The Avision backend hasn't changed in some time (early 2015 was the
last release, I think), which rather points the problem elsewhere.
Unfortunately there are at least four possible culprits:

-  Kernel changes
-  libusb changes
-  Problems in the scanner itself
-  Problems in your PC.

To pin this down I'd suggest a classic "change one part at a time"
elimination test sequence.  What you might try:

-  Test the scanner with the current Ubuntu/SANE distribution on
   another PC.  If it scans OK there, this would rather rule out the
   scanner itself as the problem.

-  Test your PC's USB setup with some non-scanner high-speed transfers.
   One way would be to plug in a USB hard driver or data stick, and then
   "dd if=/dev/sdB bs=$((1024*1024)) of=/dev/null" (substitute the
   correct device identifier) and see if the transfer works successfully
   or if it triggers the USB hang.

   (Based on what you report, I've got a nasty feeling that your
motherboard host controller may be ill... works OK for low-speed
transfers, but hangs up somehow during sustained high-speed
transfers.  The fact that it times out and leaves the bus hung
is troubling.)

-  Boot up a different Linux distribution on your laptop (e.g. Knoppix)
   and see if you can get the scanner to work reliably.  If so it might
   point to a recent change in your normal kernel and/or libusb as
   being responsible.

Hello Dave,

I'm suffering from "avision" trouble as well (you may have read my
recent posts to this list).
I'd like to offer my ubuntu 16.10 / hp7400c setup for further testing.
I sent my log files to this list on Nov 7th, maybe they can be useful.

Cheers,

Hi, David.  I just ran into a similar problem with an HP 8300 I
purchased (used).  I've written up a patch for it (and another for an
additional problem) and I can send them to you this evening.  You will,
unfortunately, have to build the SANE backends from source in order to
use this - as far as I can tell there's no way to work around the
problem without a fix to the Avision backend.

This is apparently a problem which has been reported for several years,
but a fix has never made it into the main SANE source distribution.

The problem is this: the 8200 family can report an inconsistent status
when queried about their "accessories" (the transparency backlight and
the ADF).  If there's no ADF attached, the 8200 and 8300 will report an
"ADF present" flag of 0 (meaning "none present") but also send an ADF
type code of 1 (an "Oodles" ADF).

There's some code in the backend which interprets this as "Oh, there's
actually an ADF there, but it's not working properly and needs to be
reset".  The code makes several attempts to reset the ADF (to get an
ADF-present code of 1) and when it fails, bails out with a "not
supported" error.  That's what you're seeing.

It's possible to just disable the retry loop in the Avision back-end
source code (which is what I did last night).  Once this is done, my
8300 was able to scan... it worked at 300, 600, and 1200 dpi.  Haven't
been able to do a 4800 dpi scan yet (I'm getting an I/O error).

The patch I came up with, adds another override option to the
"avision.conf" file.  If you add a "skip-adf" override, the backend will
accept the "ADF not present" status and will not try to repeatedly
reset the ADF.  It should still be able to use an ADF if one is present
and is reported properly.

The other fix I'm working on has to do with the transparency/slide
backlight.  If you select this (via "-source Transparency") the backend
will scan once.  During subsequent scans, it gets confused as to whether
the lamp is on or not, and just sits there for 90 seconds (I think it'll
still scan after that but it's an annoying wait).  My patch should be
able to adjust the lamp-polling code to recognize the "transparency
backlight lamp is on" status properly.

I'm planning to submit these patches to the SANE master branch once I
test 'em out a bit further.
