[sane-devel] Fujitsu iX500 - No scanners were identified.

[Jiri]

Hi,

[Debian Sid]

I started having problem with Fujitsu iX500 scanner after upgrade. It
used to work fine, but now it seems the system identifies the scanner
for a just a while and but apps cannot use it.

Here is example. I run the following command two times right after each
other. The scanner is recognized on first run (after plugging USB in),
but when I run it second time it says the scanner was not identified.

Any help would be appreciated.

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).

Thanks Jiri

You did not tell us what you upgraded? Sane-backends, your scanner, your kernel?

This sounds like a pretty typical linux usb bug. You might need to
install a development version of sane-backends from our git repo. Once
you have built and installed a sane-backends git snapshot (using the
info in README.linux), you can run scanimage -L repeatedly. You may
find that the scanner only shows up intermittently. If that is the
case, try running this repeatedly instead:

SANE_USB_WORKAROUND=1 scanimage -L

That might work better. If so, you will have to put
SANE_USB_WORKAROUND=1 into your environment.

Oh, and BTW, your scanner is not supported by the snapscan backend.
Try fujitsu instead.

Hi,
[Debian Sid]
I started having problem with Fujitsu iX500 scanner after upgrade. It used
to work fine, but now it seems the system identifies the scanner for a just
a while and but apps cannot use it.
Here is example. I run the following command two times right after each
other. The scanner is recognized on first run (after plugging USB in), but
when I run it second time it says the scanner was not identified.
Any help would be appreciated.

What was the outcome from my suggestions last year?

Hi,
1. When I use USB 3.0 Type B Plug connector (cable which comes with the
scanner), scanimage -L recognizes the scanner only once and applications like
Simple Scan or Skanlite are not able to scan.
2. However when I use USB 2.0 Type B Plug connector (i used cable from my
externar HDD), everything seems to work just fine.
My notebook has got all USB ports USB 3.0 and I don't have USB 2 hub to test.
Anyway using cable with old USB 2.0 B plug is simple workaround.
If I can provide any debug data, which can help to fix the issue, please let me
know and I can provide it for both cables.

You did not tell us what you upgraded? Sane-backends, your scanner, your kernel?
This sounds like a pretty typical linux usb bug. You might need to
install a development version of sane-backends from our git repo. Once
you have built and installed a sane-backends git snapshot (using the
info in README.linux), you can run scanimage -L repeatedly. You may
find that the scanner only shows up intermittently. If that is the
SANE_USB_WORKAROUND=1 scanimage -L
That might work better. If so, you will have to put
SANE_USB_WORKAROUND=1 into your environment.
Oh, and BTW, your scanner is not supported by the snapscan backend.
Try fujitsu instead.

Hi,
[Debian Sid]
I started having problem with Fujitsu iX500 scanner after upgrade. It used
to work fine, but now it seems the system identifies the scanner for a just
a while and but apps cannot use it.
Here is example. I run the following command two times right after each
other. The scanner is recognized on first run (after plugging USB in), but
when I run it second time it says the scanner was not identified.
Any help would be appreciated.

The SANE_USB_WORKAROUND env var was added in sane-backends 1.0.27, so
I recommend an upgrade.

allan

Hi Allan,
Thank you for your response. I really appreciate it.
Currently I have latest sane-backends from Debian SID. Do I have to install
the developer version or the SANE_USB_WORKAROUND variable also works in
current debian version? As a workaround I might prefer to use the USB 2.0
Type B plug until everything is fixed in the future or until I get new
scanner. This is much easier workaround then maintaining the developer
version. :). I can also try the experimental repo with sane-backends
(1.0.27-1~experimental2) if needed.
Here are some details for you.

What was the outcome from my suggestions last year?
allan

Hi,
1. When I use USB 3.0 Type B Plug connector (cable which comes with the
scanner), scanimage -L recognizes the scanner only once and applications
like Simple Scan or Skanlite are not able to scan.
2. However when I use USB 2.0 Type B Plug connector (i used cable from my
externar HDD), everything seems to work just fine.
My notebook has got all USB ports USB 3.0 and I don't have USB 2 hub to
test.
Anyway using cable with old USB 2.0 B plug is simple workaround.
If I can provide any debug data, which can help to fix the issue, please
let me know and I can provide it for both cables.

You did not tell us what you upgraded? Sane-backends, your scanner,
your
kernel?
This sounds like a pretty typical linux usb bug. You might need to
install a development version of sane-backends from our git repo. Once
you have built and installed a sane-backends git snapshot (using the
info in README.linux), you can run scanimage -L repeatedly. You may
find that the scanner only shows up intermittently. If that is the
SANE_USB_WORKAROUND=1 scanimage -L
That might work better. If so, you will have to put
SANE_USB_WORKAROUND=1 into your environment.
Oh, and BTW, your scanner is not supported by the snapscan backend.
Try fujitsu instead.

Hi,
[Debian Sid]
I started having problem with Fujitsu iX500 scanner after upgrade. It
used
to work fine, but now it seems the system identifies the scanner for
a
just
a while and but apps cannot use it.
Here is example. I run the following command two times right after each
other. The scanner is recognized on first run (after plugging USB in),
but
when I run it second time it says the scanner was not identified.
Any help would be appreciated.
