Dear Cedric,
Please take into consideration that I am not a SANE expert, nor a Canon
LIDE expert.
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).
Everything else is built on top of those sane backends, through a very
simple API layer.
If scanimage from a terminal works for your scanner, then your scanner
works with SANE.
Your problem is not scanner related.
Google is your friend.
Have you tried these:
http://askubuntu.com/questions/599694/scanimage-works-but-xsane-or-any-other-ui-does-not
Or the more commented:
http://unix.stackexchange.com/questions/191777/scanimage-works-but-xsane-or-any-other-ui-does-not
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).
The reason you are not getting a response from this list, is probably
that your problem is not SANE-related.
You may not be a techie now, but you'll get sucked into it sooner or
later. Use Google.
Best regards,
Stijn

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

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 ?
Hi,
I have the same problem with the LIDE 210. In a message from last
month, Stef
asked for usbpcap log from windows (see
http://lists.alioth.debian.org/pipermail/sane-devel/2015-March/033202.ht
ml
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
I have no windows installed. I have one in a KVM box, should I give it a
try ?
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.
So,
Is this dump (from a virtulized windows seeing USB2) interesting ?
Regards
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
