This guide is written for people who want to use their UMTS/HSDPA Card with Gentoo Linux. The first part of this guide will tell you what kernel options you will need to get the hardware working. The next part will be the configuration for the datacard to establish a ppp connection to your provider. In the explained case the provider is SFR from France.

[edit] Kernel configuration
USB to Serial converter for the Modem is necessary. To establish the PPP connection to the provider, ppp support also has to be enabled in the kernel.
| Linux Kernel Configuration: 2.6.27-gentoo-r8 - USB and PPP setup |
Device Drivers ->
USB support --->
<M> OHCI HCD support (If not use Intel or VIA chipset)
<M> UHCI HCD (most Intel and VIA) support (If use Intel or VIA chipset)
<M> USB Serial Converter support --->
[*] USB Generic Serial Driver
<M> USB driver for GSM and CDMA modems
Network device support --->
<*> PPP (point-to-point protocol) support
<*> PPP support for async serial ports
|
Recompile the kernel and reboot or/and load the newly enabled modules.
[edit] Hardware detection
After loading the necessary modules, plug the modem and wait for a few seconds and check that ttyUSB* devices are created.
usbserial: USB Serial support registered for GSM modem (1-port) option: USB Driver for GSM modems: v0.7.2 option 4-1:1.0: GSM modem (1-port) converter detected usb 4-1: GSM modem (1-port) converter now attached to ttyUSB0 option 4-1:1.1: GSM modem (1-port) converter detected usb 4-1: GSM modem (1-port) converter now attached to ttyUSB1
In this case ttyUSB0/1 are created, this might differe if you already have others usb/serial controllers pluged. Check that devices are actually created.
crw-rw---- 1 root uucp 188, 0 2009-03-15 17:48 /dev/ttyUSB0 crw-rw---- 1 root uucp 188, 1 2009-03-15 17:48 /dev/ttyUSB1
Vendor and Product ID can be found by typing lsusb command
Bus 004 Device 003: ID 12d1:1003 Huawei Technologies Co., Ltd. E220 HSDPA Modem
Last thing to do regarding hardware is to make sure that the user has access to serial port, it has to be a member of the uucp group.
In some cases you'll need to use sys-apps/usb_modeswitch software to disable an embedded usb storage
[edit] Software
[edit] KDE kppp
You need have net-dialup/ppp first.
In Model table, add a new model at /dev/ttyUSB0 (or others), Flow control set to Hardware, termination = CR and speed = 460800. Add extra command at Modem table if you need enter PIN password
AT+CPIN= [your PIN]
Add a new account and tel number please refer for wvdail session as your telcom setting. For Chunghwa Telcom is
*99#
Input both Username and password are dummy.
[edit] Vodafone
Vodafone provide a nice UI interface write in python, but only one version seems to work (sometimes) with gentoo

[edit] wvdial
You need have net-dialup/ppp first.
To establish the connexion emerge wvdial if not done yet and edit its configuration file with root priviledges. Below is an example of a configuration used for SFR network in France, you will have to search for a configuration that suits your provider:
[Dialer Defaults] Baud = 460800 ISDN = false Init1 = AT+CPIN=6451 Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 Init3 = AT+CGDCONT=16,"IP","websfr" Modem = /dev/ttyUSB0 Modem Type = Analog Modem username=dummy password=dummy Phone = *99***16#
Nota: For SFR in France you may have to use this configuration if previous one doesn't work for /etc/wvdial.conf
[Dialer Defaults] Modem = /dev/ttyUSB0
[Dialer pin] Modem = /dev/ttyUSB0 Baud = 115200 Dial Attempts = 2 Init1 = ATZ Init2 = AT+CPIN=<your pin number> Init3 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
[Dialer Vodafone] Init1 = ATZ Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 Init3 = AT+CGDCONT=1,"IP","slsfr" Modem Type = Analog Modem Baud = 115200 New PPPD = yes Modem = /dev/ttyUSB0 ISDN = 0 Dial Command = ATDT Phone = "*99***1#" Password = "slsfr" Username = "slsfr"
and you have to do so to connect
wvdial pin : initialize the modem wvdial Vodafone : connect to internet
This is for Australia's Network 3 (Three):
[Dialer Defaults] Init1 = ATZ Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 Check Def Route = on Phone = *99# Modem Type = Analog Modem Stupid Mode = 1 Baud = 9600 Dial Command = ATDT Dial Attempts = 3 Modem = /dev/ttyUSB0 ISDN = 0 Password = dummy Username = dummy
[Dialer connect] Init2 = ATZ Init3 = ATE0V1&D2&C1S0=0+IFC=2,2 Init4 = AT+CGDCONT=1,"IP","$apn" ISDN = 0 Modem = /dev/ttyUSB1 Modem Type = Analog Modem Baud = 460800
This is for Finland's Network Saunalahti:
[Dialer Defaults] Init = AT+CGDCONT=1,"IP","internet.saunalahti" Init1 = ATZ Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 Stupid Mode = 1 Modem Type = Analog Modem Phone = *99***1# ISDN = 0 Username = " " Password = " " Modem = /dev/ttyUSB0 Baud = 9600
For Chunghwa Telcom (中華電信) Taiwan :
[Dialer Defaults] Phone = *99# APN = internet Username = pummy Password = pummy Stupid Mode = 1 Dial Command = ATDT Modem = /dev/ttyUSB0 Baud = 460800 Init1 = ATZ Init2 = AT+CPIN= [your PIN password] (if need) Init3 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 ISDN = 0 Modem Type = Analog Modem
Now it's time to establish the connection, open a console with your user and run wvdial.

Connection is now established, you can check that the network interface is up and it has an ip address:
ppp0 Link encap:Point-to-Point Protocol
inet addr:10.162.164.227 P-t-P:10.64.64.64 Mask:255.255.255.255

The modem should have a fixed green light if connected in 2G, a blue light if connected in 3G, you should now be connected to the internet.
