================================================== =====================

The Huawei E220 is a USB 'dongle' for HSDPA connection through (for me, 
anyway) the Vodaphone network in New Zealand.

When inserted into a Ubuntu OS, it is immediately detected as a 
SCSI/CDROM type bulk storage device, and the files that are used by 
Windows appear attached to the filesystem similar to any other USB 
storage device.

Close any window that might be showing you those files. Then unmount the 
device (eject the CDROM icon you'll find on the desktop created when you 
inserted the device).

All commands I give here are just the commands - you will likely need to 
put *'sudo'* in front of them so you have the permissions of root to 
carry them out...

Insert the device and give it a chance to settle down (enjoy watching 
the lights flash...)

When you insert the device and it gets recognised as a storage device, 
it will have created /dev/ttyUSB0. You can see that with:

*ls -la /dev/ttyU**

You will likely only see one entry: ttyUSB0.

To make the modem work, you must first remove the module that is used 
for usb-storage devices. You can do that with:

*rmmod usb-storage*

If you are told it is in use, that is an indication you didn't close 
windows and eject the device first.

This next command may not be absolutely necessary, but it won't hurt 
anything (heh, heh...):

*rmmod usb-serial*

You are now going to re-insert that module, but giving the specific 
details of your modem. First, make sure you have the right details by using:


You should see an entry similar to this in the output:

*Bus 004 Device 004: ID 12d1:1003 *

The Bus and/or Device number might be different for you, but the 
important part is the ID. If yours is not 12d1:1003, you'll need to 
modify the next command, but I *think* it will be either that or 

This command will insert the module with the device specific details:

*modprobe usbserial vendor=0x12d1 product=0x1003*

Now, remove the device, wait a bit for things to settle, and then plug 
it back in.

I *think* you may now have maybe three entries if you do:

ls -la /dev/ttyU*

Basically, what has been done is that you have removed the initial 
inclination to treat the device only as a bulk storage (removing the 
module that handles that). You've also manually caused the recognition 
of the device (using the modprobe command). So that when you re-plugged 
it, it should now be able to work with the *modem* part of the device 
addressing it as /dev/ttyUSB0, rather than that being the bulk storage 

Use a text editor such as pico to edit or create if necessary the file 
to handle the dialling configuration. My /etc/wvdial.conf file looks 
like this:

*# wvdial for Vodacom Data. Created by Tazz_tux
# Version 1.0

# Change Log:
# Added support for HSDPA.
# Added Headers and version control.

[Dialer Defaults]
Phone = *99***1#
Username = username
Password = password
Stupid Mode = 1
Dial Command = ATDT

[Dialer hsdpa]
Modem = /dev/ttyUSB0
Baud = 460800
Init2 = ATZ
Init3 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
ISDN = 0
Modem Type = Analog Modem

I've only put in the relevant sections - the full file can be found at 
the address below this posting.

You can dial the modem with:

*wvdial hsdpa*

If all is happy, you'll see the messages in the terminal window to show 
how it is connecting, your IP address, your remote gateway and 2 
nameservers the network provides for you.

Do remember the various need for 'sudo' unless you change 
ownerships/permissions. In particular, if it looks like you've connected 
but are not able to connect to any sites, etc, look for a message 
telling you that /etc/ppp/pap-secrets and /etc/ppp/chap-secrets are not 
able to be written to - that may well indicate that you for sure need to 
run the wvdial command as sudo (If you are running it as a normal user, 
that user would need to have the ability to write to those files for the 
connection to be able to work...)

I am writing this while standing on the shoulders of the knowledgeable 
and the helpful. In particular, see 
http://www.mybroadband.co.za/vb/showthread.php?t=21726 - Post 1 in that 
thread, and Tazz_Tux who wrote and maintains it, has been invaluable. Go 
there if for no other reason than to get the latest version of wvdial.conf

Enjoy your Huawei E220 under Ubuntu!
