Dear Cedric,<br>
<br>
Please take into consideration that I am not a SANE expert, nor a
Canon LIDE expert.<br>
<br>
SANE is a modular structure. The dirty under-the-hood work that
scanner drivers do to get a scanner working, is abstracted away to
"SANE drivers" (i.e. backends).<br>
Everything else is built on top of those sane backends, through a
very simple API layer.<br>
<br>
If scanimage from a terminal works for your scanner, then your
scanner works with SANE.<br>
Your problem is not scanner related.<br>
<br>
Google is your friend.<br>
Have you tried these:<br>
<a class="moz-txt-link-freetext" href="http://askubuntu.com/questions/599694/scanimage-works-but-xsane-or-any-other-ui-does-not">http://askubuntu.com/questions/599694/scanimage-works-but-xsane-or-any-other-ui-does-not</a><br>
Or the more commented:
<a class="moz-txt-link-freetext" href="http://unix.stackexchange.com/questions/191777/scanimage-works-but-xsane-or-any-other-ui-does-not">http://unix.stackexchange.com/questions/191777/scanimage-works-but-xsane-or-any-other-ui-does-not</a><br>
<br>
Both refer to a problem with the way linux handles USB. This has
indeed changed a few times over the years, causing un-linux like
situations where something works one time, and then stops working
(e.g. after an update).<br>
<br>
The reason you are not getting a response from this list, is
probably that your problem is not SANE-related.<br>
You may not be a techie now, but you'll get sucked into it sooner or
later. Use Google.<br>
<br>
<br>
Best regards,<br>
<br>
Stijn<br>

A good day to everybody.<br>
<br>
I keep reading about flatbed scanners from Canon (in particular of
the LIDE <br>
series) not working when USB-plugged in under Linux but working
fine under<br>
Windows. I have exactly the same problem with a LIDE 25 and an HP
4400c <br>
scanner. <br>
<br>
Yes, both scanners are old but they are in excellent condition,
(very low<br>
mileage + many years forgotten somewhere in their original
packing). Both <br>
work flawlessly under legacy Windows XP as well as under Win 7 on
different <br>
machines, including one that runs a dual Lx/Win boot.<br>
<br>
As far as 'sane' front-ends go, I downloaded and installed two
from the Ubuntu <br>
Software Center and tried them repeatedly.<br>
- simple scan 3.12.1<br>
- xsane 0.998 whose author I even contacted, Oliver Rauch, hoping
for pointers. <br>
Unfortunately I got no answer.<br>
<br>
Nothing seems to work under Linux with a 'sane' based gui for
those two scanners,<br>
BUT:<br>
-1- it was not always the case. Up until about 8-10 weeks ago,
xsane used to work <br>
flawlessly for me. Nothing in my system (hard and soft) changed
since then,<br>
apart from regular stable and security related updates as provided
by Canonical.<br>
-2- I can scan w/o an itch from my Ubuntu terminal using
'scanimage'. I do that <br>
on a daily basis with no errors. <br>
<br>
I already wrote about that here, about 40 days ago, and got a
resounding silence<br>
 for an answer. No idea why.<br>
<br>
Anyway I believe this is completely unrelated to the USB3 issue
that is now widely <br>
publicized. This probably has to do with some change in the kernel
AND the way <br>
the two afore mentionned 'sane' based gui packages handle
communication with <br>
the scanner or the daemon that handles USB comm. or some' else.<br>
Something happened about 8 to 10 weeks go and I don't know what it
is.<br>
<br>
Since I am no techie, I am stuck, but at least 'scanimage' on
terminal works. <br>
The downside with scanimage is despite all available options<br>
- no preview is available (pre-processing),<br>
- no collating batch (multi-page) scans (post-processing) is
possible,<br>
- there is no saving scans directly as pdf (post-processing).<br>

<pre wrap="">Hi,
I've got a brand new computer with USB3 all over the place, and cannot
use my "old" LIDE 110 with it, even with a git version. The scanner is
still working, as it works when connecter to my older laptop, through
USB2. It doesn't work with a git checkout from a few minutes ago.
I see that some drivers have received some patches to work around
problems with USB 3. Is there something to be done to the genesys
driver
too ? What can I provide to help solving this ?

<pre wrap="">Hi,
I have the same problem with the LIDE 210. In a message from last
month, Stef
asked for usbpcap log from windows (see
<a moz-do-not-send="true" class="moz-txt-link-freetext" href="http://lists.alioth.debian.org/pipermail/sane-devel/2015-March/033202.ht">http://lists.alioth.debian.org/pipermail/sane-devel/2015-March/033202.ht</a>

for details). Unfortunately I don't have access to a Windows
computer having
USB3 ports. So if you have and you could provide those logs, it might
help in
figuring out what's going wrong.
Grs,
Heinz

<pre wrap="">I have no windows installed. I have one in a KVM box, should I give it a

<pre wrap="">I gave it a try, in the KVM windows, scanning works. It is seen as USB2
from windows though, I don't know if this is of any importance.
</pre>

<pre wrap="">So,
Is this dump (from a virtulized windows seeing USB2) interesting ?

</pre>
</blockquote>
<pre wrap="">Hi,
I'm back on this, after a while away from home. Is there anything I can
provide ?
To sum up:
- The LIDE110 doesn't work from SANE (git checkout from 10 minutes ago) +
Linux (4.0.5): I only have problem with the scanner. Any other periphal I
plugged in worked ok (mouse, usb card reader, usb disk drive, keyboard)?
- It works in Win7, virtualized in KVM, using the exact same USB3 port (seen
as USB2 from Windows)
- It almost works when all debug traces are activated in SANE (it fails much
later)
I am willing to capture anything you want, just tell me (and give me pointers
to how to do the requested captures). I could even (but as a last resort, as I
don't have space for it right now) install a Win7 on this machine.
Regards
