Oki, i have read a a shitload of howto´s and never got the complete story so now to let other people off a bit easier i write this quick guide...

[EDIT]
This should of cause work with ANY 3G operator that uses Huawei E220.
You just have to change your "Phone" number and APN.
[/EDIT]


First of all you need to get the USB device identified by your computer and to do that wee need to modify our drivers a bit.
This is no less then the "Airprime" module. (Yes i know you can use the "usbserial" to but not with full speed compability)
So lets open the "/usr/src/linux/drivers/usb/serial/airprime.c" and se

Now look for this line:
Code:

static struct usb_device_id id_table [] = {


below you will se lines like this:
Code:

        { USB_DEVICE(0x0c88, 0x17da) }, /* Kyocera Wireless KPC650/Passport */


Now add the folowing line right below the static struct line:
Code:

        { USB_DEVICE(0x12d1, 0x1003) }, /* Huawei E220 */


So the two first lines in "airprime.c" starting from the "static struct" line will look like this:
Code:

static struct usb_device_id id_table [] = {
        { USB_DEVICE(0x12d1, 0x1003) }, /* Huawei E220 */


Now save it and enter kernel config by doing the following:
Code:

~ # cd /usr/src/linux
linux # make menuconfig


Now youhave to add support for you device as a module, So you have to add the following to you kernel.
Code:

Device Drivers  --->
 USB support  --->
  USB Serial Converter support  --->
   <M> USB Serial Converter support
    [*]   USB Generic Serial Driver
    <M>   USB AirPrime CDMA Wireless Driver


Now exit saving changes and recompile your kernel by doing:
Code:

make && make modules_install


Now you have you module complete and if you shouldnt havae to restart your computer unless it´s a new version on your new kernel.
So now you can load your module by doing like this.
Code:

modeprobe airprime


Now you should be able to see your new device in /dev, it´s full path is /dev/ttyUSB0.



So now to the connection part....

First we need a program to actually handle the "modem" connection, i choose wvdial.
so compile in wvdial and then continue.

Now we have to create a wvdial config file with all the right options and stuff so i do it the easiest way, i´ll let you have mine ;)
Code:

[Dialer Defaults]
Stupid Mode = 1
Modem = /dev/ttyUSB0
Modem Type = Analog Modem
Dial Command = ATDT
ISDN = 0
Baud = 460800
Phone = *99*data.tre.se#
Username = user
Password = pass

[Dialer PIN]
Init1 = AT+CPIN=XXXX

[Dialer PINOFF]
Init1 = AT+CLCK="SC",0,"XXXX"

[Dialer PINON]
Init1 = AT+CLCK="SC",1,"XXXX"

[Dialer 3G]
Init2 = ATZ
Init3 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0

(DON´T FORGET TO REPLACE THE XXXX WITH YOUR OWN PIN CODE)


And when you have saved that one you should only have to start the program by doing this:
Code:

wvdial PIN 3G

(YOU ONLY USE THE "PIN" PARAMETER THE FIRST TIME TO ACCESS THE MODEM)

So nex time if no computer restart or unplugging of the modem has been done u just use this:
Code:

wvdial 3G


If that dosen´t work you could try the old version of connecting.
This is just another way to make the connection wich they used to use.

So here comes my old config:
Code:

[Dialer Defaults]
Stupid Mode = 1
Modem = /dev/ttyUSB0
Modem Type = Analog Modem
Dial Command = ATDT
ISDN = 0
Baud = 460800
Phone = *99#
Username = user
Password = pass

[Dialer PIN]
Init1 = AT+CPIN=XXXX

[Dialer PINOFF]
Init1 = AT+CLCK="SC",0,"XXXX"

[Dialer PINON]
Init1 = AT+CLCK="SC",1,"XXXX"

[Dialer 3G]
Init2 = ATZ
Init3 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0

[Dialer DATA]
Init4 = AT+CGDCONT=1,"IP","data.tre.se"

(DON´T FORGET TO REPLACE THE XXXX WITH YOUR OWN PIN CODE)

And the command to use this version of conf is this:
Code:

wvdial PIN 3G DATA


Or if it´s not the first time:
Code:

wvdial 3G DATA




The only diffrerens is as i said how you connects, so here is an explanation.
Phone is more or less the number you dial, so with the "new" config you connect by specifying all you need in you "number" like this.
*99*APN*LinkProtocol*CID#
Ex: Phone = *99*data.tre.se#
Or: Phone = *99*data.tre.se*IP*1# <-- is exactly the same as old version with another command.

In the "old" config you specify evetrything in a "Define PDP Context" command known as AT+CGDCONT like this
AT+CGDCONT=CID,"LinkProtocol","APN"
Ex: AT+CGDCONT=1,"IP","data.tre.se"

This link explains AT+CGDCONT and GPRS AT commands abit more:
http://www.phonestar.com.my/s_at_10.html


If you wanna permanently turn you pin off you cand do so by executing the following command:
Code:

wvdial PINOFF


And to turn it on just type:
Code:

wvdial PINON


And USERNAME and PASSWORD is not important so just leave them be.



So just for your information:
At least my operator TRE has multiple APN´s wich is the "data.tre.se" part, you can use any of them and i can give you two here
[list=]
APN1: data.tre.se
APN2: bredband.tre.se
[/list]

And if you know any more or maybe some for another provider please post them here.


Hope you have som use of this, and happy halloween ehh or something.....

Have you tried the older version ? (old config and "wvdial 3G DATA")
As i said in the tutorial some of the providers dont support the newer method...

@xanthax

did you tried with the usbserial solution before?
I have mine running with this howto but dont like the solution because I need
to start pppd config twice and the udev script doesnt run very well.

Don't you have problems with the usb-storage initial state of device using this driver?
What do you mean with full speed of usbserial driver?

I have this speed ( got it from shitty german web speed test )

===============================================
DSL Speedtest http://www.speedreport.de

Download-Speed: 26 kb/s (204 kbit/s)
Upload: 20 kb/s (156 kbit/s)
Ping: 0,27 ms
measurement on 07.08.2007 at 14:14:29 o clock
===============================================

I want to try your solution too but don't want to struggle (again) with these usb_storage problems...

To try and answer your questions.

I think the "option" serial driver is actually the one to use. If you look at the help for that driver it lists Huawei as one of the manufacturers it supports. Having tried the Generic, Airprime and Option drivers, the Generic one doesn't support the full speed of the e220 (somebody told me the e220 will go up to 14Mbps, obviously the network has to support that). The only discernable differences I can make out between Airprime and Option are Airprime creates more /dev/ttyUSBx's and doesn't run as smoothly (at least for me anyway).

If you are using a new enough kernel (2.6.20 or above) you won't have issues with usb-storage.

For completeness here are the relevant sections of my kernel config and /etc/conf.d/net:-

)

Obviously you will need to put the correct apn information in the chat script and possibly username and password for pppd to use (my settings are for 3Ireland). You should also disable the pin on the sim using your mobile phone (mine came disabled).

In short you should have little problem getting this working without any hacks and full Gentoo init script support. I get bursts of upto 2Mbps but I have never had the full 3.6 that my ISP advertises. I don't know whether that is a limitation of the network conditions here or the option driver. But hey it works and is reliable enough.

Hi jpl888,

thanks for posting your config and answering my questions.

I was unsure if options is the right way to go when I first saw xanthax post with airprime driver.
I am using option all the time and have some issues also with newer kernel

Code:
Linux gentoo 2.6.21-suspend2-r7 #1 SMP Wed Sep 19 21:50:00 CEST 2007 i686 AMD Opteron(tm) Processor 146 AuthenticAMD GNU/Linux

Code:
Linux gentoo 2.6.20-suspend2-r6 #1 SMP Wed Sep 19 21:50:00 CEST 2007 i686 AMD Opteron(tm) Processor 146 AuthenticAMD GNU/Linux


I have an udev script from https://forums.gentoo.org/viewtopic-t-523964-highlight-huawei.html running for connection.
Did your modem runs out of the box without doing some of these steps?

For me on bootup with 2.6.21 only one /dev/ttyUSBx entry appears. pppd daemon than refuses to work. I need to use a active usb-cable extension (active means it is identified as hub via kernel) because without having modem near my window I only get fallback to gprs.

Yesterday, I had some interruption when connected via utms. dmesg says

Quote:
Sep 19 17:31:09 gentoo usb 1-5.1: USB disconnect, address 5
-> Is this usb or modem related?

The options driver also states to try the FTDI driver if not working correct, didn't tried that,yet.

EDIT: I have only speed of a max. 691 kbit/s (86 kByte/s) KB/sec. do I have some possibility in speed control? I commented the 460800 out of the chapscript.

My kernel is:-
Code:

Linux tux 2.6.22-gentoo-r5 #18 Wed Sep 19 14:24:35 IST 2007 x86_64 AMD Turion(tm) 64 Mobile Technology MK-38 AuthenticAMD GNU/Linux


When I first installed the laptop it had 2.6.21-gentoo-r4.

I don't use any special udev script to create the device nodes maybe that is where you are going wrong, perhaps you should delete your udev config and re-emerge it? Other than using the correct kernel config and /etc/conf.d/net I don't think I did anything else special. I can do the setup again from scratch on another machine if that would make you feel better.

My dmesg says:-

Code:
usb 2-1: GSM modem (1-port) converter now attached to ttyUSB0
usb 2-1: GSM modem (1-port) converter now attached to ttyUSB1


when the e220 is attached. I have 2 cables one very short another a few feet long with 2 connectors on. Works with both but use the longer cable in the hope I get better connection.

Your disconnect problems are USB related I suspect (unless the modem is faulty).

The speed your are describing certainly isn't unusual for me, but it does burst higher regularly, I would suggest that your local network conditions are responsible. Still at 86k per second its still much better than dial up or ISDN.

AFAIK there is no way to control the speed and the modem is adaptive trying to get the best connection possible.

You're right.
I have found this thread related to my problem and I am know thinking about changing usb onboard against an usb 2.0 pci card.

your also right, for me currently under
Code:
Linux gentoo 2.6.21-suspend2-r7 #3 SMP Thu Sep 20 14:07:19 CEST 2007 i686 AMD Opteron(tm) Processor 146 AuthenticAMD GNU/Linux


initialisation works (on boot) without the udev script. It needs some more restart / replug tests to see if it (modem initialisation) is stable.

Being right was bound to happen sooner or later. Kind of like the theoretical monkeys eventually creating the works of Shakespeare if you give them long enough ;)

I am basking in the glory as I write this ... bask.

Right enough basking now back to being wrong!

BTW I think that Schopenhaur quote is spot on, my take on it would be "It's never as easy as you think it will be"

FYI I happened to see the short log for the last RC of 2.6.23

The kernel guys think the option driver is the right one to use too!

The tests with another usb card yesterday gets awkward.
I change kernel back to gentoo-soruces, currently using suspend2 on all my boxes but it has no features for my old opteron 146, only keeping consistence.

Obviosly I have to say more "thanks, that has done the trick" instead of "you're right" :wink:

Your catch with schopenhaur is right ( oh I did it again ) - spending days easily, with one! problem gives you a real feeling of what is the meaning of easy.

Yes but then you know much more about how these yokes work now than if it had been easy. The amount you get out is directly proportional to the amount you put in.

I have some more tips which may or may not improve your experience, these may just be 3 Ireland specific but I would imagine they configure HSDPA networks in much the same way in different countries.

1. You can bypass the transparent proxy (which may be crap) on [Insert your provider here]'s HSDPA network by getting an IPV6 address and tunnel. For instance in Europe from www.sixxs.net

2. Don't use the DNS servers provided by the ISP instead use OpenDNS or something like that (these servers seem to be more reliable at least).

3. If you need a public IP (and you can't use your IPV6 address) and you have access to a customer/friend's DSL connection, you can create a VPN using OpenVPN and route relevant incoming traffic to your machine through the VPN tunnel using policy routing (I haven't done this yet, although I know it is possible).

To give an example use of 3. for some reason I cannot send out large emails, the connection breaks in the middle of sending and times out, so what I did yesterday was tell OpenVPN to route all traffic and sent the email through that. The VPN seems to be much better at recovering from an unstable link than bog standard tcp/ip.

apart, if you're doing the same thing over and over - like compiling "option" in kernel, as modules "usb_storage" in kernel or as modules whole uhci,ohci,ehci in kernel as option in the hope that these disconnects will went over.
The effort done is not worth to ( beside you're as internet addicted as me ) . The look in the kernel changelog from your side was way more faster :D

my chatscript looks:

ABORT BUSY
ABORT 'NO CARRIER'
ABORT VOICE
ABORT 'NO DIALTONE'
ABORT 'NO DIAL TONE'
ABORT 'NO ANSWER'
ABORT DELAYED
# modeminit
'' ATZ
ABORT 'NO CARRIER'
ABORT ERROR
REPORT CONNECT
TIMEOUT 10
OK AT+CPIN? READY-AT+CPIN=<DOYOUNEEDTHIS?>-OK ""
TIMEOUT 20
'' 'AT+cgdcont=1,"IP","Internet.eplus.de"' OK "ATDT*99***1#"  -> is this APN? Internet.eplus.de
SAY "Calling Base Internet Flatrate\n"
TIMEOUT 60
CONNECT \d\c

2. Don't use the DNS servers


I know that provider based are not usable from other internet connections. Have to get on universal for both dsl / umts here than also manually edit resolv.conf will come to an end.

3. If you need a public IP


Hm, ok I understand that tunneling (includes vpn) sometimes is better for stability of connection, I used to access my box through http tunnel with ssh out of my old company. But for clarifying: public IP did work for incoming umts / gprs or is there some hitch?

Did you already tried to play with MTU Settings?

I also wonder if this is possible. Would have a need for stress testing the connection as the modem one day will become my customers one...

test with 2.6.23-rc7 (vanilla-sources) when plug in the modem afterwards booting:

Code:
Sep 22 11:37:12 gentoo usb 1-6.1: new full speed USB device using ehci_hcd and address 10
Sep 22 11:37:12 gentoo usb 1-6.1: configuration #1 chosen from 1 choice
Sep 22 11:37:12 gentoo scsi5 : SCSI emulation for USB Mass Storage devices
Sep 22 11:37:12 gentoo usb-storage: device found at 10
Sep 22 11:37:12 gentoo usb-storage: waiting for device to settle before scanning
Sep 22 11:37:17 gentoo scsi 5:0:0:0: CD-ROM            HUAWEI   Mass Storage     2.31 PQ: 0 ANSI: 2
Sep 22 11:37:17 gentoo sr1: scsi-1 drive
Sep 22 11:37:17 gentoo sr 5:0:0:0: Attached scsi CD-ROM sr1
Sep 22 11:37:17 gentoo sr 5:0:0:0: Attached scsi generic sg2 type 5
Sep 22 11:37:17 gentoo usb-storage: device scan complete


*argh* at least i thought that would work now.

OK, Here it has been som activity while i have been gone...

I see jpl888 and tekknokrat has found a few solutions to some of the problems.

Still at the time when i did my install Airprime where the only driver that included high speed connection which usb-serial didnt as "Standard".
You could remove a buffer max size in the driver but that didnt work for me so Airprime was the only real way to use it then if you wanted to get any good speed.

But now it seems that the usb-serial driver worked just fine, but there is still things about the 3G network like response time, dips and much more that makes it worthless as a replacement for ADSL or Cabel connections...

So unless you ONLY use it for surfing and email stick to a wired connection.

And thanks to "jpl888" and "tekknokrat" for picking up where i left of...
