problème de droits sur utilisation scanner.

[bsd29 AT free POINT fr]

Bonsoir,

J'ai besoin de votre aide pour faire fonctionner mon scanner Canon
(CanoScan Lide 25).Je tourne sur OpenBSD-4.1, noyau générique.
J'ai installé le paquet sane-backends.


Je ne parviens pas à utiliser mon scanner en simple utilisateur...Il me semble
pourtant avoir changer les permissions adéquates. Où est donc le problème ?


$dmesg | grep Canon
ugen0: Canon CanoScan, rev 1.10/1.00,addr 2

$sane-find-scanner -q
found USB scanner (vendor=0x04a9 [Canon], product=0x2220 [CanoScan], chip=LM9832
/3) at libusb:/dev/usb0:/dev/ugen0

$scanimage -L
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).

#scanimage -L
device `plustek:libusb:/dev/usb0:/dev/ugen0' is a Canon LiDE25 USB flatbed
scanner
