[sane-devel] Fujitsu ScanSnap iX500 "Brain-dead scanner" in SANE 1.0.25

[Krutzbeuazen]

Dear list,

I try to get a new Fujitsu ScanSnap iX500 to work on Debian 7.4 x64. The
scanner works on this machine with some proprietary software which
doesn't use SANE.

I installed SANE from source, both into the regular folders and with
./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var
I still have the original out-dated SANE installed, as the new manually
installed SANE doesn't resolve the xsane dependencies here.

For testing I set
> sudo chmod -R a+w /dev/bus/usb/*
Normally an UDEV rule and the user being in 'plugdev' 'scanner' 'saned'
groups is supposed to set all permissions right.


I removed all other scanner/USB-IDs from the SANE config(s) and set the
buffer to 65536. With original configs the symptoms were the same.

The first time I try to talk to the scanner, it seems to respond. From
the second time on, it seems dead. Only re-plugging the USB lets me talk
to it again, for one time.
I never got the scanner to physically do anything, like pulling paper or
changing the status LEDs.

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).

At this point I am lost here.
I would consider setting up a dedicated linux box for this, on another
distro if needed. The preferred solution would be to get it running on
my desktop computer, though ;-)

I am grateful for any hints.
Please let me know if my way of formatting (and exporting to a pastebin)
needs to be improved for mailinglists too.

Cheers from Germany,
