Ubuntu guide to using HSDPA USB-modem Huawei E220 with the Tre network

Using the Huawei E220 under Linux is not supported by the 3G operator 3 (in Swedish: Tre ..). Here’s a guide how to get it working on Ubuntu.
Your connection have a pin-code per default set. Its written on your larger sim-card adapter. In order to simplify alot, lets just remove this. Put the 3g data simcard in your 3g-phone and remove the sim pin. Then put the card into the USB-modem.
If you start up your Ubuntu machine and plug in the USB-modem, it will show as a cd-rom drive (atleast my does). Also I’m getting a folder popping up as if it would be a storage device (it does seems to be a storage device for windows drivers..).
- First step, right click on the newly auto-created cd-rom icon on your desktop and choose eject. Close any windows using the device.
- Start a terminal. The commands below should be ran as root.
rmmod usb-storage
rmmod usbserial
(the later might create an error.)
lsusb
- The last command shoul show the device connected similiar to:
Bus 001 Device 003: ID 12d1:1003
Run:
modprobe usbserial vendor=0×12d1 product=0×1003
Now, disconnect the Huawei E220 USB-modem and wait a few seconds before connecting it again.
- As soon as the device have stopped blinking green you should find three new USB-devices by running the command:
ls -al /dev/ttyU*
Now its time to setup the wvdial.conf file. This config works for me, given that the pin sim-code is removed it whould work right off for you aswell. That is if you have a swedish tre.se turbo3g or 3g data account.
[Dialer Defaults]
Init2 = ATZ
Init3 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Stupid Mode = 1
Modem Type = Analog Modem
ISDN = 0
Phone = *99***1#
Modem = /dev/ttyUSB0
Username = user
Dial Command = ATDT
Password = pass
Baud = 460800
Init4 = AT+CGDCONT=1,"IP","data.tre.se"
You should now be able to run the command:
wvdial
And the log might look something like this:

For your information.. The latest Ubuntu beta (7.04) detects the modem from start. Then you only will need the wvdial.conf file..

Im having no luck.
The modem is registred by the system.
But when running wvdail im getting no responce from it.
from dmesg:

Olangu: What version of ubuntu are you running?
Is it the Huawei e220? Does dmesg say anything about finding three different devices?

I have the same problem with my HSDPA modem as “olangu” had. I have Ubuntu 2.6.15-28-686 kernel. The system does recognize the modem, but doesn’t say anything about finding different three devices. How to get through in this case???
