Newer udev (060 or so) puts itself as the hotplug program in /proc/sys/kernel/hotplug, but doesn't handle firmware loading requests, thus the automatic firmware loading as described below won't work. Please see this bug report for more details: http://bugs.archlinux.org/task/3439 - this issue is fixed in udev>071.

Introduction

This howto shows one way to get a working speedtouch USB modem. It uses the kernel driver, not the userspace driver. This howto assumes that your ISP uses PPPoA and not PPPoE. For info about PPPoE with these modems see first url below.

Important sites where most info comes from:

If the below instructions are not enough to get it working, then read the above sites.

The following steps are needed to get the modem working:

Kernel config and ppp

Make sure you have a kernel with the proper support (at least the modules ppp_generic, pppoatm, slhc, atm, usbatm and speedtch). The default Arch kernel should work.

Otherwise make sure that your kernel supports firmware loading:

$ zgrep FW_LOADER /proc/config.gz 

Install ppp: pacman -S ppp

The Arch Way

netcfg

Tango-view-refresh-red.pngThis article or section is out of date.Tango-view-refresh-red.png

Reason: netcfg has been superseded by netctl, but there is no package like netctl-pppoa. In fact, this is the only page on ArchWiki mentioning pppoa. (Discuss in Talk:DSL SpeedTouch modem#)

Install the package netcfg-pppoaAUR.

Now configure the connection. We'll put it in /etc/network.d/adsl:

CONNECTION='pppoa'
DESCRIPTION='ADSL connection'
INTERFACE='ppp0'
USER='username'
PASSWORD='password'
PPPOA_VPI=8
PPPOA_VCI=48

# This causes pppd to reconnect if the link goes down
LCP_ECHO_INTERVAL=15
LCP_ECHO_FAILURE=10

You should now be able to connect by calling netcfg adsl. For more details, see the netcfg wiki page.

The manual way

Configuring pppd

###  /etc/ppp/peers/speedtch

# To connect to using this configuration file, do
#       pppd call speedtch

lcp-echo-interval 10
lcp-echo-failure 10
noipdefault
defaultroute
user "username@ispname"
noauth
noaccomp
nopcomp
noccp
novj
holdoff 4
persist
maxfail 25
updetach
usepeerdns
plugin pppoatm.so
# Following entry is country/ISP dependent
8.48

The last entry depends on your country/ISP and is created from the VPI and VCI setting in the format VPI.VCI. This page has a VPI / VCI Setting List.

You also need to configure /etc/ppp/pap-secrets or chap-secrets, depending on your ISP. pap-secrets files are of the format:

# Secrets for authentication using PAP
# client        server  secret		IP addresses
"ISP-Username"	*	ISP-password	*

See The PAP/CHAP secrets file for more details.

If you want to use the DNS servers provided by your ISP (you probably do!) then make a symlink /etc/resolv.conf pointing to /etc/ppp/resolv.conf:

cd etc
rm resolv.conf
ln -s ppp/resolv.conf resolv.conf

Configure udev

Make a file /etc/udev/rules.d/99-speedtouch.rules and put something like the following in it:

ACTION=="add", SUBSYSTEM=="atm", KERNEL=="speedtch*", RUN="/usr/bin/pppd call speedtch"

With this Udev will start pppd automatically, if you do not want this you can simply bring up your modem using

pppd call speedtch

Firmware

Now you have everything except the firmware loading. The easiest way is to let udev do it. Download rev4fw.zip (note disclaimer here) and unzip it. It contains two files, a small one and a big one. Copy the small file to /usr/lib/firmware/speedtch-1.bin and the big one to /usr/lib/firmware/speedtch-2.bin

# mkdir -p /usr/lib/firmware
# cp small_file /usr/lib/firmware/speedtch-1.bin
# cp large_file /usr/lib/firmware/speedtch-2.bin

If you cannot download this file then follow the instructions of the second link above and use the firmware extractor (or download another firmware which has the two files).

Troubleshooting

If the modem is being detected correctly and the firmware is loading, you should see something like the following in dmesg:

usbcore: registered new driver speedtch
usb 1-1: found stage 1 firmware speedtch-1.bin
CSLIP: code copyright 1989 Regents of the University of California
PPP generic driver version 2.4.2
usb 1-1: found stage 2 firmware speedtch-2.bin
ip_tables: (C) 2000-2002 Netfilter core team
ADSL line is synchronising
DSL line goes up
ADSL line is up (800 Kib/s down || 256 Kib/s up)

pppd output in /var/log/messages should look something like:

Plugin pppoatm.so loaded.
PPPoATM plugin_init
PPPoATM setdevname - remove unwanted options
PPPoATM setdevname_pppoatm - SUCCESS:8.48
Using interface ppp0
Connect: ppp0 <--> 8.48
PAP authentication succeeded
local  IP address 123.45.67.89
remote IP address 195.190.249.10
primary   DNS address 195.121.1.34
secondary DNS address 195.121.1.66

If you are having problems you can check pppd debug messages by adding debug to /etc/ppp/peers/speedtch. This can help identify authentication problems (e.g. pap vs chap auth), etc. Otherwise make sure you check your VPI/VCI settings!
