[sane-devel] Scanner Canon - CanoScan 300, udev rules missing?

[Marek Straka]

My original /etc/sane.d/canon.conf

#canon.conf
/dev/scanner
#/dev/sg0


I have tried following alternatives

#canon.conf
/dev/scanner
/dev/sg0

or

#canon.conf
/dev/scanner
#/dev/sg0
scsi CANON IX

in both cases same behaviour:

First try:
tata at dell:~$ scanimage -L
Neoprávněný přístup do paměti (SIGSEGV)    (it means not allowed access to memory)

...but second try:
tata at dell:~$ scanimage -L
device `canon:/dev/sg0' is a CANON IX-03035B        flatbed scanner

and from this point is xsane working normally. If I restart computer I need again start scanimage -L two times. What is this?
