Installing an Epson 3170 USB Scanner on Xandros
Not all distributions are created equal and one of the places that may show is in the USB scanner devices provided. Should these be missing on your system, you need to add these yourself. For the Debian-based Xandros distribution, this is the case.
Note that this only applies to USB scanner devices for kernels that do not use the device file system, a.k.a. devfs. Again, for the Xandros distribution, this is the case. (i.e. Xandros does not use devfs, so these instructions apply).

For Xandros 3
If you have Xandros 3, see Xandros3Kwikis. You can install the "iscan" package straight from the ArchLUG APT repositories
You will also need to install the iscan plugin package that is specific to your model of Epson Scanner:
Plugin Package Non-Free Lib Firmware iscan-plugin-gt-7200 libesint1F.so iscan-plugin-gt-7300 libesint23.so iscan-plugin-gt-9400 (3170) libesint32.so esfw32.bin iscan-plugin-gt-f500 libesint41.so esfw41.bin iscan-plugin-gt-f520 libesint52.so esfw52.bin iscan-plugin-gt-f600 libesint43.so esfw43.bin iscan-plugin-gt-x750 libesint54.so esfw54.bin
After that, you will need to restart your hotplug service by running '/etc/init.d/xandros-hotplug restart'
You can find more information about the Linux drivers for Epson products at the Epkowa/Avasys site
A word about Image Scan
While Image Scan is nice and quite functional, I have found Ed Hamrick's VueScan (http://www.hamrick.com/) to be unbelievably useful, and worth the nominal fee he charges for it. It is a huge timesaver if you are scanning slides, since it can batch scan all four slides with the holder, color-correct them, and auto-name them with an incrementing counter. And the Pro version will enable color calibration features to calibrate targets with your slides, prints, and your printer. Highly recommended if you're going to be doing lots of scanning, or your scanning needs are to supplement your photography hobby and/or professional interests.
If you do decide to take a look at VueScan, you will still need to install the Epkowa SANE back-end as described below, and then you will need to run the following command:
cd /usr/lib ; ln -s iscan/libesint32.so libesint32.so
And add the following to the end of your /etc/profile file:
export SANEI_EPKOWA_FIRMWAREFILE=/usr/share/iscan/esfw32.bin
And finally, make sure that you've added or enabled the 'epkowa' driver and disabled the 'epson' driver in /etc/sane.d/dll.conf.
Epkowa appears to have removed the firmware images from the distributed RPM, so you will need to extract it from the source tarball in the non-free directory. Or, you can use a direct link to esfw32.bin here
Getting the Gimp to use iScan
ln -s /usr/bin/iscan /usr/lib/gimp/2.0/plug-ins/
For Xandros 2
Pre-requisites
First off, you should use Xandros Networks to install the following packages. You will need to enable the 'Debian unsupported site' to do so, and use the Search feature, looking in the Expert section of the Search Results.
- C/C++ Development Tools
- Install this from the normal package tree section of Xandros Networks (no 'Expert' search or 'Debian unsupported site' necessary)
- This 'package' is really just gcc, make, and a bunch of other goodies all bundled for convenience
- sane sane-utils xsane libsane-dev
- libjpeg-mmx-progs libjpeg-mmx-dev libjpeg62 libjpeg62-dev libpng12-dev
- gdk-imlib1 gdk-imlib1-dev libgtk1.2-dev libgimp1.2-dev
- libtool libltdl3 libltdl3-dev
Get the Epkowa SANE backend
Then you'll need to download the Epkowa SANE backend drivers from here:
- http://www.avasys.jp/english/linux_e/dl_scan.html
- When filling out their survey, tell them you have a "Debian" version of Linux.
- Download the Source file for 'gcc-3.2'. In my case, as of 2004-07-10, it was 'iscan-1.9.0-5.redhat.8.0.tar.gz'.
Create your scanner device
First of all, you need to check what device name to use. This is specified in /etc/sane.d/epson.conf and most likely is set to /dev/usb/scanner0. I will use that in the remainder, adjust if necessary. The USB scanner devices are allotted major 180 and minors from 48 to 63, so you can use up to 16 USB scanners with your system. Scanner users will need read and write access to the device. Device nodes are made with the mknod and usually requires root permissions.
If that was all Greek to you, don't worry, here are the commands to add a working /dev/usb/scanner0:
# mknod /dev/usb/scanner0 c 180 48 # chmod 0666 /dev/usb/scanner0
The 'mknod' command creates the device. The 'c' indicates that a scanner is a character device, and the '180' is the 'major' device number reserved for USB scanner devices. The '48' is the first 'minor' device number in the range 48 through 63, reserved for the first scanner device. For additional scanners, simply increase the minor device number by one for each scanner, giving you a maximum of 16 connected scanners.
If you have more USB scanners
Additional USB scanner devices may be added with something like:
# mknod /dev/usb/scanner1 c 180 49 # chmod 0666 /dev/usb/scanner1
Advanced Security Options
If you do not understand this next section, skip it.
For the security conscious amongst you, you may not want to give blanket write access (that final 6 in 0666) to the scanner, but create a group for all users that may operate a scanner and use a more restrictive permission mask, at most 0664, on the devices. Let's say you want to add a scanner group with users sam and robin and make the access permissions are restrictive as possible. You do that with:
# groupadd scanner # chgrp scanner /dev/usb/scanner0 # chmod 0660 /dev/usb/scanner0 # for user in sam robin; do useradd -G scanner $user; done
Loading the Linux driver
For the Epson 3170, you will need to verify the USB Vendor and Product codes assigned for your scanner. You can see them by issuing the command:
# cat /proc/bus/usb/devices
Look for the line:
S: Product=EPSON Scanner
And above it, you should see a line similar to:
P: Vendor=04b8 ProdID=0116 Rev= 1.00
If you have a different scanner, the Vendor and ProdID values may be different. And if you have a different version of the scanner firmware, the Revision value may be different as well.
To load the USB scanner support, issue the command (substituting your Vendor and Product ID codes, which are hexadecimal values, and will require a '0x' prefix):
# insmod scanner vendor=0x04b8 product=0x0116
To make this permanently load in your Xandros system, add the following line to the end of the /etc/devices/drivers file.
90 scanner vendor=0x04b8 product=0x0116
Then, run the xangenmodules program as root to regenerate the /etc/modules file.
Compiling Image Scan
Unpack the Epkowa Image Scan for Linux package:
tar xzvf iscan-1.9.0-5.redhat.8.0.tar.gz
Configure, Compile and Install (as root):
# Change directories to where the iscan package unpacked itself cd iscan-1.9.0 # # Configure the package ./configure # # Compile the package make # # Become the 'root' user to install the iscan package # You will be moved to the 'root' user's home directory. su - # # Change directories back to where you compiled iscan cd /home/<your_username>/iscan-1.9.0 # # Install the package make install # # You are done, go back to being a regular user exit
Putting in the magic smoke to make it work
If you try to run iscan, you'll get the following error:
iscan: error while loading shared libraries: libesmod.so.1: cannot open shared object file: No such file or directory
So here's the magic you won't find anywhere else that makes it work:
You now need to also tell Xandros to look in /usr/local/lib for the libraries that were installed. To do that add the following line to the /etc/ld.so.conf file:
/usr/local/lib
You may need to either reboot your system or run the 'ldconfig' command, because this information is cached when the system comes up.
For versions prior to 1.6:
- It turns out that the non-free Epkowa library, libesint32.so, was compiled with the wrong path for the (also non-free) scanner firmware binary file. Since we don't have the source code, we can't fix this with a re-compile. Creating the link described below fixes the problem.
cd /usr/share; ln -s /usr/local/share/iscan iscan
Using your new scanner
Simply run the command 'iscan'. You can setup shortcuts and menu options as you like.
Enjoy!
