Exécution d’un scanner Epson Perfection 3170 sous Ubuntu 14.04

Question

C'est le même problème que j'ai eu pour Ubuntu 11.04: Exécution d'un epson Scanner perfection 317 mais je ne peux pas l'appliquer pour Ubuntu 14.04.

J'ai installé les deux iscan_2.10.0-2_i386.deb & iscan-plugin-gt-9400_1.0.0-2_i386.deb

$ Sudo sane-find-scanner | grep -i epson found USB scanner (vendor=0x04b8 [EPSON], product=0x0116 [EPSON Scanner]) at libusb:002:003 $ Sudo scanimage -L device `epson:libusb:002:003' is a Epson � flatbed scanner $ tail /etc/sane.d/epson.conf usb 0x04b8 0x0116 $ Sudo sane-find-scanner | grep -i epson found USB scanner (vendor=0x04b8 [EPSON], product=0x0116 [EPSON Scanner]) at libusb:002:003 $ head /etc/udev/rules.d/50-libsane-extras.rules SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", SYSFS{idVendor}=="04b8", SYSFS{idProduct}=="0116", MODE="0666", GROUP="scanner" $ groups lindenb lindenb : lindenb adm dialout cdrom plugdev lpadmin admin saned sambashare scanner

iscan: (impossible d'envoyer une commande au scanner)

Sudo iscan: (impossible d'envoyer une commande au scanner)

Savez-vous comment résoudre ce problème s'il vous plaît?

Ce que j'ai fait:

Désinstallez les paquets sane/xsane/... installés par Ubuntu.

Cloner sane-backend de git et l'installer

./configure --enable-libusb_1_0 --disable-translations --prefix=/usr --sysconfdir=/etc

Cloner sane-frontend de git et l'installer

./configure --prefix=/usr --sysconfdir=/etc

Editer /etc/sane.d/dll.conf: Mettez en commentaire epson et epson scan. Ajoutez epkowa qui manquait dans ce fichier.
Le fichier /etc/sane.d/epkowa.conf était manquant. J'ai ajouté le usb-id pour mon scanner.
```
$ grep -vE '^#' /etc/sane.d/epkowa.conf scsi EPSON usb usb 0x04b8 0x0116 
```
Installez iscan et son plugin à partir du RPM disponible chez Epson
Redémarrer

J'avais des problèmes similaires avec un Epson Perfection 3170 et Ubuntu 12.04. J'ai essayé toutes les règles sane.d, epkowa, udev mais je ne voulais pas utiliser le clone git. J'ai donc essayé d'utiliser le PPA ppa:rolfbensch/sane-git de Rolf Bensch, toujours sans succès.

Je me suis rappelé avoir vu un message d'erreur précédent relatif à l'absence de libjpeg62; après l'avoir installé, xsane a fonctionné!
