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). 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
