[sane-devel] Cannot connect to my Fujitsu ScanSnap S1300i:

[Max Westen]

Trying to get my installation going.
Running Arch-Linux 4.13.12-1-ARCH on an Apple MacBookPro3,1.

Installed Sane by using sudo pacman -S sane
Installed version is: 1.0.27

A scan for the device gives me the following:
[***@Luminox sane.d]$ sane-find-scanner -q

I've installed the file 1300i_0D12.nal in /usr/share/sane/epjitsu as per
instructions of man sane-epjitsu and made sure the file
/etc/sane.d/epjitsu.conf has the correct line for the firmware and usb

I commented out all other devices except for net and apjitsu in
/etc/sane.d/dll.conf, to minimise waittime.

when issuing the command scanimage -L it gives me no device.

after doing an export SANE_DEBUG_EPJITSU=30 and thn giving a scanimage -L,
it gives me the following output:

[***@Luminox sane.d]$ scanimage -L
[sanei_debug] Setting debug level of epjitsu to 30.

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).

[epjitsu] sane_exit: finish


I'm not sure what to do next......
Does anyone have a hint as where to search for a solution ?

Thanks in advance!

Follow up:

Tried the other USB-port.
detecting the scanner gives me a hit. Immediately rescanning and the device
is 'gone':

[***@Luminox test]$ scanadf -L
device `epjitsu:libusb:002:002' is a FUJITSU ScanSnap S1300i scanner
[***@Luminox test]$ scanadf -L
[***@Luminox test]$


After some trying, this behaviour keeps the same...

I've prepared a comammandline with the next USB instance, unplug the USB,
put it back in and then execute the command. Yay it works !

[***@Luminox test]$ scanadf -d "epjitsu:libusb:002:009" --source "ADF
Duplex" --mode Color --resolution 300dpi -o /tmp/20171204_113055/page_%04d
--page-height 376
scanadf: rounded value of page-height from 376 to 375.999
Scanned document /tmp/20171204_113055/page_0001
Scanned document /tmp/20171204_113055/page_0002
Scanned 2 pages
[***@Luminox test]$ scanadf -L
device `epjitsu:libusb:002:009' is a FUJITSU ScanSnap S1300i scanner
[***@Luminox test]$ scanadf -L
[***@Luminox test]$

but immediately running a scanadf -L afterwards, gets me the correct ID,
giving the command another time, makes it disappear....

I can't get my head around this, but this isn't really workable....


Any help is greatly appreciated!

Sounds like the typical Linux USB problem. Please see this statement
from the sane 1.0.27 release notes:

Note 3: The Linux USB3 workaround which was added in version 1.0.25 is
now disabled by default. If you have difficulty using a scanner which
previously worked, or intermittent scanner availability, try setting
the new environment variable SANE_USB_WORKAROUND=1 before starting
your frontend.

Please give this a try, and let us know if it helps.

Hi Allan,

I've tried setting the env setting SANE_USB_WORKAROUND=1 before connecting
my scanner.
Output is still the same. The first scanimage -L returns the device. The
second (or sometimes the third time) calling the same line and it's gone.

I've looked at the specs of this macbookpro; it only contains 2 USB 2.0
ports, so it shouldn't be a USB 3 issue....

https://everymac.com/systems/apple/macbook_pro/specs/macbook-pro-core-2-duo-2.2-15-santa-rosa-specs.html

I also tried installing Arch (same setup as on macbookpro) with sane on
another laptop lying around (with lower specs, so definately not usable as
workstation) and the same scanner and that works flawless.... :(

Is there anything I could try or anything I could do to try to get it
resolved ?

Thanks again!

Max

Well, you could git bisect between sane-backends 1.0.25 and 1.0.27,
and find the commit where it breaks.

Can you show the command you used to set the env var?

Mea culpa!

Found the culprit....
SANE DID work..... but I had scanbd installed too, so scanbd had the usb
connection with sane and kept the device locked.....
I disabled scanbd, as I remembered installing that and that it might
interfere with SANE... and so it did!

Sorry for having bothered you and thanks for the help!

Well, make sure scanbd and the sane backend have their own dll.conf
where scanbd uses the "normal" one (including the backend for your
scanner), and give the normal clients only see the net backend as you
normally would for saned.

Configure scanbd to use the a separate directory where your copy the
relevant config for your backend and a dll.conf that is configured for
your backend. Remove all backends from the normal dll.conf (normally in
/etc/saned.d) but the net backend

All frontends will then use net to connect to scanbd/saned that in its
turn connects to the scanner

Hi Louis,

Thanks, I do have only 'net' in the /etc/sane.d/dll.conf and only 'epjitsu'
in the /etc/scanbd/sane.d/dll.conf
Scanning using the button works (YAY!), but connecting via the net config
fails....
logging gives me this when issuing a scanimage -L:
