Hi All,
I have a problem that just started with my scanner permissions. I can't
access it by any means unless I am root. I am running a mix of Sarge
and Sid using the 2.6.15-k7 kernel.
Running sane-find-scanner or scanimage -L as root correctly identifies
my scanner, an HP 6200C. Running the same commands as a regular user
does not find scanner. I am a member of both the scanner and saned
groups. This has been working correctly for quite some time as I built
this system more than a year ago and have been using the scanner up to
now. It has been a couple of months since I have used the scanner and
there have been a lot of updates since then so I can't tell you what all
has changed on my system since I last used it.
Some other irregularities that show up are that occasionally running
scanimage -L as root won't find the scanner either and I have also had
it report a segmentation fault. When that happened I made sure all my
usb utilities and libsane were all from Sid and it hasn't occured since.
If I try to run scanimage as root from the bash prompt here are the
results I get.
Job:/home/ffreeloader# scanimage -d hp:libusb:002:003 --format tiff >>

scanimage: sane_read: Error during device I/O
The scanner will attempt to start--goes into it's warmup cycle--but
after a few aborted attempts at starting a scan it will quit. The error
message is given before all scanner activity stops.
