ho recentemente installato una ubuntu server 10.10 su un vecchio computer per crearmi un server casalingo.
Il mio problema risiede nel fatto che dovendo scannerizzare immagini con uno scanner HP ScanJet 5400C, ho installato sane e sane-utils.
Quando ho testato lo scanner da utente root, tutto finzionava.
Quando ho provato a scannerizzare un'immagine con un'utonto qualsiasi mi dice che non ci sono scanner.
Ecco i vari comandi eseguiti:
da root:
Codice: Seleziona tutto
root@kidexo:/# scanimage -L
device `hp5400:libusb:003:005' is a Hewlett-Packard HP54xx Flatbed Scanner flatbed scanner
root@kidexo:/# sane-find-scanner
# sane-find-scanner will now attempt to detect your scanner. If the
# result is different from what you expected, first make sure your
# scanner is powered up and properly connected to your computer.
# No SCSI scanners found. If you expected something different, make sure that
# you have loaded a kernel SCSI driver for your SCSI adapter.

# 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.Codice: Seleziona tutto

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).

Grazie,
