[sane-devel] fujitsu fi-4120c2 problems

[Giuseppe Sacco]

Hi all,
today I have been working with a fi-4120c2 scanner. I used my sane
1.0.17 (debian package 1.0.17-1) but I coundn't scan any page.
I was working on a powerc linux 2.6.16.

sane-find-scanner found the scanner, while scanimage -L did not.

My command line for scanning was:

$ sudo env SANE_DEBUG_SANEI_USB=255 SANE_DEBUG_FUJITSU=255 \
  scanimage  -d fujitsu:libusb:002:010 >immagine 2>log

and the process was looping. I killed it after one minute since the ADF
wasn't loading the sheet.

The log file is like this:

with the last lines showing the endless loop. The complete log is

Anyone knows how to workaround or fix the problem?

Thanks,
