1.1 Description

EciAdsl is a free Linux driver for connecting your computer to the internet, if you have a Globespan based ADSL USB modem.
Other operating systems like *BSD are under development (please contact authors for more information - See Authors / Support.)

EciAdsl driver homepage is there:

An up-to-date list of supported modems is available on this page:

1.2 Pre-requisites

1.2.1 Packages

In order to install EciAdsl driver, you need the following programs/packages:

1.2.2 Kernel

If you have latest Mandrake/Redhat with default kernel you can skip this chapter.
According to your distribution, some options may lack in your kernel. If eciadsl-doctor detects missing options, then you need to recompile your kernel.

You MUST include these options (“*” stands for “in the kernel”, “M” stands for “module”):

USB support —>
<M> Support for USB
[ ] USB verbose debug messages
— Miscellaneous USB options
[*] Preliminary USB device filesystem
[ ] Enforce USB bandwidth allocation (EXPERIMENTAL)

2 Installation

Next: , Previous: Installation, Up: Installation

2.1 Removing dabusb

If modem is powered on at Linux startup, then you need to remove dabusb.
Otherwise, skip this section.

Hotplug is probably enabled, and it wrongly detects your modems as an audio device and loads dabusb module in order to add support for this audio device.
If /etc/hotplug/blacklist exists, edit it and add a line containing the word 'dabusb' (without the quotes) to it. Restart Linux.

If you cannot find such file whereas hotplug is installed and enabled, there must be another way to configure it, but you can also apply the following method (a bit rough):

If the kernel has been compiled by hand, don't forget to remove dabusb support from the kernel configuration too.

2.2 Driver installation

Download the latest stable usermode package (source code or a package for your distrubution) on this page:

Depending of the package you get, issue one of these commands:

where x.y is the version (for example 0.8)

Previous: Driver installation, Up: Installation

2.3 Compilation

If you installed distro specific package (Redhat/Mandrake, Debian, Slackware, Gentoo), you can skip this step.

All you have to do is to run in a console or a terminal:
As "root": make install

Check ./configure –help to get a list of optional settings. You may want to install the software in a different place than the default one (/usr/local), using --prefix=/opt for instance.
Driver's config files can also be installed in a directory you may prefer (default is in /etc/eciadsl), using the –conf-prefix (default is /) AND –conf-fir (default is etc/eciadsl) parameters. For instance:
--conf-prefix=/opt --conf-dir=etc/eciadsl
or --conf-prefix=/opt/eciadsl --conf-dir=etc

Be careful, –etc-prefix can be changed too (defaut is /, so /etc is used), but it is used to get system config files like resolv.conf or the pppd config files. Use –etc-prefix only if you know what you are doing.

See other options using ./configure –help.

3.1 Configuration tool

Previous: Configuration tool, Up: Configuration

3.2 Detail of parameters

Username given by your provider
For example: username@clubadsl1

Password given by your provider

First number of “dialed number”
For example if you “dial” 8,35 with Windows driver then your VPI is 8.

Second number of “dialed number”
For example if you “dial” 8,35 with Windows driver then your VCI is 35.

Provider DNS
Check the box “Update provider DNS” and choose your provider in the list.
If your provider is not in the list, enter manually your DNS servers in the fields below the list.
If you don't know your DNS servers, read this question in FAQ:

Select your modem in the list.
If your modem is not in the list, check on modems page:
- If your modem is “not supported”, the driver will never work with your modem (please don't ask for support to developers, you've to look for another driver).
- If your modem is “maybe supported”, then ask to developers for detail. See Authors / Support.

Modem chipset
[value is automatically setted by choosing Modem model].
For any doubt please check on modems page:

Alt synch
[value is automatically setted by choosing Modem model].
It is the USB alt interface used by eciadsl to comunicate with modems during synch phase.
Standard values: 4 for GS7070 (old modem models) - 5 or 0 for GS7470 chipset (new modem models)
For any doubt please check on modems page:

Alt pppoeci
[value is automatically setted by choosing Modem model].
It is the USB alt interface used by eciadsl to comunicate with modems during pppoeci phase.
Standard values: 4 for GS7070 (old modem models) - 1 or 0 for GS7470 chipset (new modem models)
For any doubt please check on modems page:

Synch .bin file
Check this option only if eciadsl-start fails with synchronization.

PPP mode
- For users in France, choose default PPP mode (VCM_RFC2364).
- For other users, check the appropriate ppp mode with your provider.
Look at this question in the FAQ:

Check this only if your provider uses DHCP.
If you don't know, leave this option unchecked.

Static IP
Check this only if you have static IP.
If so, enter IP address and gateway below.
If you don't know, leave this option unchecked.

4 Connection

Next: , Previous: Connection, Up: Connection

4.1 Eciadsl-start

To connect to the internet, issue this command as root:
eciadsl-start | tee log.txt

4.1.1 Synch problem

If you've problems with synch (eciadsl-synch timeout/error or lcp timeouts after synch), then follow instructions below:

For other problems with eciadsl-start, please look at the FAQ:

4.1.2 PPPoE users

If you're using PPPoE, you have to configure and use a standard PPPoE client as rp-pppoe ( to connect to your ADSL modem through tap0.

Previous: Eciadsl-start, Up: Connection

4.2 Other scripts

4.2.1 eciadsl-probe-device

Use this script if eciadsl-start doesn't find your modem. This script looks for VID/PID of your modem and display them. For detail, please contact us. See Authors / Support.

4.2.2 eciadsl-doctor

Use this script (with --usb-init option) if eciadsl-start fails with other problem than “Modem not found” or synchronization.

4.2.3 eciadsl-probe-synch

Use this script to test automatically all .bin files, if you have synch problems.

Next: , Previous: Connection, Up: Top

5 Synch .bin creation

If you've synch problems and tried all .bin files with no success, then you have to create your own .bin file under Windows.

Otherwise, you can skip this chapter.

5.1 Eci Windows driver

[Skip this section if your modem has a GS7470 chipset, YOU MUST USE YOUR OWN WINDOWS DRIVER.
For any doubt please check your modem chipset at:].

5.1.1 Download

Download Eci windows driver version 1.06 (otherwise your .bin file will not work under linux):

5.1.2 Driver modification

If your modem has not one of these VID/PID, you've to modify two files in Eci Windows:
- VID1/PID1: 0547/2131, VID2/PID2: 0915/8000
- VID1/PID1: 0915/0001, VID2/PID2: 0915/0002
To check your VID/PID, please look at:

Modifications you've to do:

- file gafwload.inf, line 24 :
ExcludeFromSelect = USB\VID_0547&PID_2131
replace 0547 by your VID1 and 2131 by your PID1

- file gafwload.inf, line 30 :
replace 0547 by your VID1 and 2131 by your PID1

- file gwausb.inf, line 34 :
ExcludeFromSelect = USB\VID_0915&PID_8000
replace 0915 by your VID2 and 8000 by your PID2

- file gwausb.inf, line 42 :
%ADSLUSB.DeviceDesc% = ADSLUSB.gspnDefault, USB\VID_0915&PID_8000
replace 0915 by your VID2 and 8000 by your PID2

- file gwausb.inf, line 58 :
HKR, Ndi, DeviceID, 0, "USB\VID_0915&PID_8000"
replace 0915 by your VID2 and 8000 by your PID2

5.1.3 Installation

Launch setup.exe and follow instructions.

5.2 USB Sniffer

Download and install latest USB sniffer package there:

Documentation for Snoopy (USB sniffer) is available there:

Next: , Previous: USB Sniffer, Up: Synch .bin creation

5.3 Sniff USB packets under Windows

Disable auto-connection to the internet and unplug all USB devices (except the modem).

Start the sniffer and install the filter on the “Wan modem”, then unplug and replug the modem.
As soon as both red and green leds are fixed, uninstall filters.
The sniffed packets should be in the file C:\WINxxx\usbsnoop.log
Reboot under Linux.

Previous: Snif USB packets under Windows, Up: Synch .bin creation

5.4 Convert log to .bin under Linux

Mount windows partition containing the usbsnoop log file so as to copy it where you want.
Issue this command: usbsnoop.log -chipset=#YOUR_MODEM_CHISPET#
substitute #YOUR_MODEM_CHISPET# with your modem chipset (GS7070 or GS7470).
For help, issue this command: -h
This perl script parses the log file and generates a new bin file (script provided with usermode package).
Issue this command:
mv #BIN_FILENAME_CREATED# /etc/eciadsl/my_synch.bin
substitute #BIN_FILENAME_CREATED with bin file name created.
and then run eciadsl-config-text to use this .bin

Run eciadsl-start...
...and cross your fingers :-)
