C'est le même problème que j'avais pour Ubuntu 11.04 : Exécution d'un Scanner perfection 3170 d'epson 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 scanneriscan : (n'a pas pu envoyer de commande au scanner)
sudo iscan : (n'a pas pu envoyer de commande au scanner)
Savez-vous comment résoudre ce problème ?
