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.

check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation

Thanks Jiri

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.

 # Your USB scanner was (probably) detected. It may or may not be
supported by
 # SANE. Try scanimage -L and read the backend's manpage.
 # Not checking for parallel port scanners.
 # Most Scanners connected to the parallel port or other proprietary
ports
 # can't be detected by this program.
 # You may want to run this program as root to find all devices. Once
you
 # found the scanner devices, be sure to adjust access permissions as
 # necessary
Again after I plug the USB in my computer...
