[gentoo-user-de] usb-Scanner wird nicht gefunden

15/07/2009 - 13:10 von Kurt Stegen-Olzog | Report spam
Guten Tag,
seit Tagen fummele ich an meinem System herum,
um meinen USB_Scanner "HP-ScanJet 8250" zum
Laufen zu bekommen. Aber egal was ich probiert habe
das Ergebnis ist leider immer das gleiche. :-(

done

und scanimage -L kommt zu folgendem Ergebnis:

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).

So langsam bin ich mit meinem Latein am Ende.
Vieleich hat ja hier jemand noch einen Tip für mich !? :-)

ps. Natürlich ist mir in der Ausgabe von sane-find-scaner
das folgende aufgefalle: "libusb not available"
aber das "usb-USE-Flag" ist gesetzt und libusb ist
installiert. :-(

Meist kommen solche Probleme dadurch zu stande, dass der Benutzer keine
Zugriffsrechts auf /dev/bus/usb/ bzw. /proc/bus/usb/ hat. Neue Scanner
sollten dort durch passende Regelsàtze der Gruppe "scanner" zugteilt werden,
unbekannte USB-Geràte der Gruppe "usb".

Der einfachste Test ob es an den Rechten liegt ist, scanimage -L mal als root
auszuführen. Wenn es da klappt, fehlen dem Benutzer irgend welche
Gruppen-Rechte.
