Non ho uno scanner e quindi non so esattamente come sia la
situazione... però:
$ ls -l /dev/scd0
brw-rw---- 1 root cdrom 11, 0 nov 4 2001 /dev/scd0
come vedi... i miei utenti sono aggiunti al gruppo cdrom.
Tu hai un nuovo gruppo "scanner" in etc/group?
Se sì allora, come si evince da
"/usr/src/linux/Documentation/devices.txt":
"""
Locally defined links
The following links may be established locally to conform to the
configuration of the system. This is merely a tabulation of existing
practice, and does not constitute a recommendation. However, if they
exist, they should have the following uses.
/dev/mouse mouse port symbolic Current mouse device
/dev/tape tape device symbolic Current tape device
/dev/cdrom CD-ROM device symbolic Current CD-ROM device
/dev/cdwriter CD-writer symbolic Current CD-writer device
/dev/scanner scanner symbolic Current scanner device
/dev/modem modem port symbolic Current dialout device
/dev/root root device symbolic Current root filesystem
/dev/swap swap device symbolic Current swap device
/dev/modem should not be used for a modem which supports dialin as
well as dialout, as it tends to cause lock file problems. If it
exists, /dev/modem should point to the appropriate primary TTY device
(the use of the alternate callout devices is deprecated).
For SCSI devices, /dev/tape and /dev/cdrom should point to the
``cooked'' devices (/dev/st* and /dev/sr*, respectively), whereas
/dev/cdwriter and /dev/scanner should point to the appropriate generic
SCSI devices (/dev/sg*).
"""
Ovvero crea /dev/scanner ed un link simbolico a /dev/sg0
Modifica sg0 in modo che abbia root:scanner ed aggiungi il tuo utente
a scanner.
Ciao
