# epkowa.conf -- sample configuration for the EPKOWA SANE backend
# Copyright (C) 2004, 2008, 2009 Olaf Meeuwissen
#
# See sane-epkowa(5), sane-usb(5) and sane-scsi(5) for details.
# Detect all devices supported by the backend.
# If you don't have a SCSI device, you can comment out the "scsi"
# keyword. Similarly for the other keywords.
#
usb
scsi
# For any USB scanner not known to the backend (yet), you may, at your
# own peril(!!), force the backend to recognise and use it via libusb.
# You can do so by the following configuration command:
#
# usb <USB vendor ID> <USB product ID>
#
# SEIKO EPSON's USB vendor ID is '0x04b8' (without quotes). In order
# to find the USB product ID, use lsusb(1).
# A sample configuration for the Epson Perfection 1650 (Epson GT-8200),
# which has a product ID of 0x0110, would look as follows:
#
usb 0x04b8 0x1121
# For SCSI devices not detected, you can add an entry like:
#
# scsi EPSON GT-20000
#
# where the GT-20000 bit corresponds to the SCSI model information as
# shown in the output of dmesg(1) or in the /var/log/kern.log file.
# Network attached devices may be made to work by first installing the
# (non-free) iscan-network-nt package and then adding configuration lines
# as per information below.
#
# For each network attached device, you must add an entry as follows:
#
# net <IP-address|hostname> [port-number]
#
# Ask your network administrator for the device's IP address or check
# for yourself on the panel (if it has one). The port-number is very
# optional and defaults to 1865.
# Note that network attached devices are not queried unless configured
# in this file.
#
# Examples:
#
#net 192.16.136.2 1865
#net 10.0.0.1
#net scanner.mydomain.com
# Some backend behaviour can be customized by using the option keyword
# followed by an option name, as shown below.
#
# option <option-name>
#
# Currently available options:
#
# Makes the automatic document feeder the default document source
#option prefer-adf
tu enregistre et quitte
puis tu redemare ton ordi
et si ca ne marche toujours pas le scann en usb ... ben je ne sais pas quoi faire de plus 🙁
