Hallo @ Alle,

ich habe mal wieder ein Problem(-chen?), welches sich warscheinlich für einen Fachmann einfach lösen läßt. Mich Laien jedoch stellt das vor ungewohnte Herausforderungen, die mich verzweifeln lassen.

Ich bräuchte bitte ganz dringend Hilfe bei der Einrichtung meines CanonScan LiDE25 unter Ubuntu 14.04 LTS (64 bit). (falls ich zu viel unnötige Informationen anfüge bitte nicht schimpfen - ich weiß nicht was man braucht und was nicht)

Folgendes als Hintergrundinformation:

Auf dem Vorgängernotebook lief er ohne Probleme.

Nur am USB Steckplatz anstrecken und gut war. dieses Notebook(HP Pavilion dv7) hatte zunächst WIN 7. Danach war es als Dualboot mit zusätzlich 12.04 LTS eingerichtet. Später als Dualboot WIN 7 / upgrade auf 14.04 LTS (64 bit).

Von daher dachte ich es wäre mit meinem "neuen" ähnlich einfach. - Dem ist nicht so.

Ich bin mir nicht wirklich sicher wie ich das angehen soll. Suchbegriffe, die mir passende Ergebnisse liefern, habe ich leider keine. Das was ich bis jetzt gefunden habe hat mich einer Lösung nicht näher gebracht (ich drehe mich gedanklich im Kreis)

Ich habe jetzt hier einen TUXEDO

Systeminformationen:
Ubuntu 14.04.2 LTS
Prozessor: Intel® Pentium(R) CPU 3550M @ 2.30GHz × 2
Grafik: Intel® Haswell Mobile 
Betriebssystem: 64 Bit

Wenn ich - wie ich das gewohnt war - Libre Office nutze und beim scannen die "Quelle auswählen" möchte dann friert Libre Office ein (das Libre Office Fenster wird dunkler). Ich kann zwar noch den Mauszeiger bewegen und andere Programme normal nutzen. Aber bei Libre Office muß ich das "Beenden erzwingen". Wenn der Scanner nicht angeschlossen ist erscheint das normale Auswahlfenster bei "Quelle Auswählen" nur dass da natürlich nichts zum Auswählen ist weil kein Scanner am USB Port hängt.

bei SIMPLE SCAN kommen folgende Fehlermeldungen: Kein Scanner gefunden Bitte überprüfen Sie, ob Ihr Scanner angeschlossen und eingeschaltet ist.

beim Scanversuch mit SIMPLE SCAN kommt: Scannen fehlgeschlagen Kein Scanner verfügbar. Bitte schließen Sie einen Scanner an.

lsusb wirft Folgendes aus:

ich habe schon alle 4 USB Steckplätze ausprobiert. Es ist überall das Selbe.

Nachdem ich erst

http://askubuntu.com/questions/364163/how-to-solve-scanner-permissions-issues

gefunden hatte und darüber auf

http://www.sane-project.org/sane-mfgs.html#Z-CANON

und auf

https://help.ubuntu.com/community/SANE%20-%20Installing%20a%20scanner%20that%20isn%27t%20auto-detected

gekommen bin dachte ich ich hätte die Lösung gefunden

Mein LiDE25 wird nämlich als "GOOD" aufgelistet

nur bei "Step 2" der Anleitung bleibe ich schon hängen, denn der Befehl

sudo gedit /etc/sane.d/dll.conf

gibt mir folgende Inhalte für das Backend:

# /etc/sane.d/dll.conf - Configuration file for the SANE dynamic backend loader
#
# Backends can also be enabled by configuration snippets under
# /etc/sane.d/dll.d directory -- packages providing backends should drop
# a config file similar to dll.conf in this directory, named after the package.
#

# The next line enables the network backend; comment it out if you don't need
# to use a remote SANE scanner over the network - see sane-net(5) and saned(8)

Wenn ich als Laie das richtig verstehe ist das # schon weg (sowohl vor canon als auch vor plustek was unter sane-project.org unter Backend steht) und deshalb ist mein Scanner nicht auskommentiert.

Trotzdem wird er wohl nicht erkannt, denn der Befehl

sane-find-scanner

liefert als Ergebnis

# 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.

Leider kann ich mit diesen ganzen Informationen nichts Anfangen. Auch habe ich keine "How-To" Beschreibungen gefunden, an denen ich mich entlang hangeln könnte.

Deshalb auf diesem Weg nochmal die Bitte: HILFE

ich komme da alleine nicht weiter.

Danke und 'Tschuldigung für den Roman

Bine

Hallo,

du hast ja eigentlich genügend Informationen (nämlich Vendor- und Product-ID des Scanners) gesammelt, um den letzten Schritt aus der von dir verlinkten Anleitung durchzuführen. Also müsste man wohl eine /etc/sane.d/plustek.conf mit diesem Inhalt anlegen:

usb 0x04a9 0x2220

Wobei es empfehlenswert ist graphische Anwendungen wie gedit nicht mit sudo, sondern mit gksudo zu starten, wenn man root-Rechte braucht.

Wenn dir dann noch die Berechtigung fehlen sollte mit deinem normalen Benutzer auf den Scanner zuzugreifen, würde ich außerdem noch eine Udev-Regel erstellen, die das ermöglicht (z.B: als /etc/udev/rules.d/40-canon_scanner.rules):

ATTRS{idVendor}=="04a9", ATTRS{idProduct}=="2220", ENV{libsane_matched}="yes"

PS: Ich weiß nicht, was dein Tuxedo-Notebook für eine Ausstattung hat, aber Probleme mit USB 2.0 Geräten an USB 3.0 Ports treten unter Linux leider ab und an auf, da wird sich mit den kommenden Kernel-Versionen hoffentlich noch einiges zum Besseren ändern.

ooooooooooh

da hatte ich wohl mal wieder reichlich Bretter vor dem Kopf

Danke 👍 habe ich gar nicht gesehen

ich werde das dann morgen gleich mal ausprobieren (wenn ich wieder aus dem Wald voller Bäume heraus bin) damit ich keine Fehler mache

😢

es klappt nicht

Libre Office hängt sich nach wie vor auf und mit Simple Scan kommen auch die selben Fehlermeldungen wie oben beschrieben

ich weiß nicht ob ich etwas falsch gemacht habe oder ob ich einen anderen Lösungsweg brauche

lsusb hat immer noch das Ergebnis wie bereits oben

sane-find-scanner gibt mir das

worauf sich ein völlig leeres gedit öffnete

da habe ich dann ATTRS{idVendor}=="04a9", ATTRS{idProduct}=="2220", ENV{libsane_matched}="yes"

eingegeben und dann abgespeichert und geschlossen

und dann das Notebook neu gestartet

was mache ich falsch?

gibt es noch etwas was ich überprüfen könnte/sollte um festzustellen, weshalb sich Libre Office aufhängt und unter Simple Scan der Scanner nicht gefunden wird?

Bitte Hilfe

traurige Grüße

ich habe mich nochmal schlau gemacht

ich habe 2 "blaue" USB Ports und 2 "graue/schwarze"

wenn gar nichts an den USB Ports angeschlossen ist sagt lsusb

Bus 002 Device 002: ID 8087:8000 Intel Corp.

Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

daher denke ich dass die 2 "blauen" USB 3.0 sind und die 2 "grauen" USB 2.0

ich habe den Scanner allerdings an allen 4 Steckplätzen ausprobiert

immer mit dem selben Ergebnis, dass Libre Office einfriert

Was passiert denn, wenn du ohne LibreOffice scannst? Vielleicht bekommt man da eine Rückmeldung, woran es hängt.

# Falls das Paket noch nicht installiert ist
sudo apt-get install sane-utils
# erkannte Scanner auflisten
scanimage -L
# Scanner-Anbindung testen
scanimage -T
# Einen Test-Scan machen
scanimage >image.pnm

Wie schon erwähnt bekomme ich mit Simple Scan die ganz oben im ersten Beitrag erwähnten Fehlermeldungen

bei SIMPLE SCAN kommen folgende Fehlermeldungen: Kein Scanner gefunden Bitte überprüfen Sie, ob Ihr Scanner angeschlossen und eingeschaltet ist.

beim Scanversuch mit SIMPLE SCAN kommt: Scannen fehlgeschlagen Kein Scanner verfügbar. Bitte schließen Sie einen Scanner an.

ich habe nochmal drüberinstalliert

wenn ich scanimage -L eingebe dauert es sehr lange und nach einer Weile stoppt das "Blinken" im Terminal (edit - der Cursor) für längere Zeit, bis das Ergebnis angezeigt wird

ausgeworfen wird dann

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).

bei scanimage -T ist es ähnlich das Blinken des Cursors stoppt irgendwann bis dann nach einer längeren Pause das Folgende ausgeworfen wird

scanimage: no SANE devices found

ich habe deshalb gar nicht erst versucht einen Test-Scan über das Terminal zu machen.

Falls das zum jetzigen Zeitpunkt dennoch sinnvoll sein sollte bitte Bescheid sagen

dann probier ich das sofort aus

Danke

Bine

Funktioniert es, wenn du die gleichen Befehle mit vorangestelltem sudo ausführst? Sieht man in der Ausgabe des Befehls

dmesg

etwas, nachdem scanimage versucht hat auf den Scanner zuzugreifen?

Ändert sich etwas, wenn der Scanner beim Booten noch nicht angeschlossen war und nachträglich angesteckt wird?

so

das hat jetzt bei mir etwas länger gedauert

also

es macht keinerlei Unterschied ob der Scanner schon beim Hochfahren angeschlossen ist oder nicht

egal an welchem Steckplatz er hängt

die Befehle sudo scanimage -L und sudo scanimage -T werfen das selbe Ergebnis aus wie schon zuvor ohne sudo

und wenn ich nach sudo scanimage -L den Befehl dmesg im Terminal eingebe kommen "Kilometer" an Informationen...(mit denen ich als Laie überhaupt nichts anfangen kann)

Etwas übersichtlicher wird es so: gebe in ein Terminal folgendes ein

tail -n 10 -f /var/log/syslog

Behalte dieses Terminal im Blick und öffne ein neues. Dann schliesst du den Scanner an. Ausgaben im 1. Terminal? Gebe im 2. Terminal ein und beobachte was passiert

scanimage -L
scanimage -T

so

wieder an der Arbeit

geöffnet kam ohne Scanner im 1. Terminal

mit scanimage -L kommt im 1. Terminal gar nix

im 2. Terminal kommt

device `plustek:libusb:003:007' is a Canon CanoScan LiDE25 flatbed scanner

mit scanimage -T wird folgendes ausgeworfen

 scanimage -T
scanimage: no SANE devices found

ich habe dann noch einmal scanimage -L eingegeben weil es ja beim ersten mal plötzlich funktioniert hatte

aber wie befürchtet kam dann wieder

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).

Hab's gerade mal selbst probiert (ich habe einen Lide20). Bei scanimage -L und bei scanimage -T passiert in beiden Fällen nichts im syslog. Ab/Anstecken des Scanners wird mit ähnlichen Meldungen wie bei dir quittiert. genauer:

May 22 14:04:23 harry2 kernel: [ 7817.248055] usb 3-1: new full-speed USB device number 3 using ohci-pci

Unterschied zu dir: using ohci-pci statt xhci-hcd (das sind die USB Kernelmodule).

Du hast also: nach dem Anstecken wird der Scanner einmalig mit scanimage -L erkannt. Danach gibt es (vermtl.) Probleme am USB. Nichts, was mit den sane conf Dateien zu tun haben könnte.

Weiter weiß ich nicht. Vielleicht mal nach Problemen mit dem xhci-hcd suchen.

😲

danke für den Hinweis

ich geh dann jetzt erst mal lesen was ich da suchen werde um ein wenig zu verstehen was ich da tue (...denn sie weiß nicht was sie tut)

Das hier scheint das selbe Problem zu sein

http://askubuntu.com/questions/457901/usb-2-0-device-scanner-does-not-work-with-xhci-hcd-on-usb-3-0-system

ich werde mal schauen ob mich das weiter bringt

falls jemand noch andere Hinweise hat würde ich mich freuen diese zu lesen

Grüße

Bine

ich habe jetzt mal klein angefangen und diesen Vorschlag in die Tat umgesetzt weil ich dachte ich kann ihn problemlos wieder rückgängig machen (hab ich dann auch)

In the UEFI/BIOS change the setting under USB configuration, "XHCI Pre-Boot mode" from enabled to disabled. In some BIOS configurations this setting is known as "XHCI Mode".

USB 3.0 ports are controlled by the xhci_hcd driver in Linux. When "XHCI pre-boot mode" is enabled the BIOS will route the USB 3.0 ports to the USB3 xHCI controller. When it is disabled, the USB 3.0 ports are routed to the EHCI (USB 2.0) ports. The wording "pre-boot mode" implies that this option only affects the environment before a full operating system is booted (the associated BIOS help text explicitly mentions that this option is used for USB3 support in MSDOS); however, it seems this can also affect the post-boot environment, and can have the effect of connecting the USB 3.0 ports to the USB 2.0 controller even after Linux is loaded (so ports run at USB2 speed).

es hat leider auch nicht geholfen

dann habe ich noch Libre Office auf Version: 4.4.3.2 gebracht

aber es hängt sich trotzdem auf wenn ich den Scanner auswählen will

für heute Abend hab ich erst mal genuch gegrübelt

mir fällt alleine im Moment nichts ein was ich noch versuchen könnte

vielleicht kommt ja morgen mit ausgeruhtem Kopf die Erleuchtung

falls jemand noch den rettenden Einfall hat - immer her damit
