ciao a tutti, il mio problema è il seguente:
ho uno scanner hp3300c che con scanimage, xscanimage funziona correttamente a patto che io usi come device:
Code:

--device-name=niash:libusb:002:002


tutti i programmi in grado di utilizzare lo scanner cercano pero tale periferica in:
/dev/scanner
io vorrei creare un link simbolico in /dev/scanner che porti a niash:libusb:002:002, il problema è che non ho idea di come si faccia, cioè non so dove sta niash:libusb:002:002 per usare ln -s, qualche idea?

kooka non lo conosco...io uso ximian openoffice...e mi vede lo scanner con libusb tranquillamente..sicuro non sia un problema di configurazione o settaggi?..per esempio se non si apportano alcune modifiche il device viene visto solo da root

non è un problema di permessi, riesco a scannerizzare come utente il problema è questo:
Code:

bash-2.05b$ sane-find-scanner -q
found USB scanner (vendor=0x03f0 [Hewlett-Packard], product=0x0205 [HP ScanJet 3300C]) at libusb:002:002
bash-2.05b$ 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).
bash-2.05b$                                         


Code:

bash-2.05b$ xscanimage niash:libusb:002:002

bash-2.05b$ xscanimage
[xscanimage] No scanners were identified. If you were expecting something
          different, check that the scanner is plugged in, turned on and
          detected by sane-find-scanner (if appropriate). Please read
          the documentation which came with this software (README, FAQ,
          manpages).


invece con;
Code:

bash-2.05b$ xscanimage niash:libusb:002:002

lo scanner funziona

deve funzionarti anche con scanimage -L
es:
Code:

josuke@minosse ~ $ scanimage -L
device `plustek:libusb:002:002' is a Hewlett-Packard Scanjet 2200c USB flatbed scanner

in effetti l'errore stava in /etc/sane.d/dll.conf
avevo decommentato la voce
Code:

hp


l'ho ricommentata ed ho aggiunto

Code:

niash

niash perchè è il backend che uso lo scanner, ora scanimage -L mi da:
Code:

bash-2.05b$ scanimage -L
device `niash:libusb:002:002' is a Hewlett-Packard ScanJet 3300C flatbed scanner
bash-2.05b$

provo con open office draw e se va aggiungo il tag risolto[/quote]
