How-to: Install modem ZTE MF626 HSDPA in Jaunty

[Unkuiri]

1) Get the latest usb_modeswitch file from the page http://www.draisberghof.de/usb_modeswitch/ from the section "Downloads"

2) click with the right button of the mouse in the file and select extract here;

3) Open the Terminal, and go to the location of the decompressed file and execute:

sudo make install

... it asks for the root password;




4) Edit the "usb_modeswitch.conf" archive. To do that execute:

sudo gedit /etc/usb_modeswitch.conf

it will open the Gnome text editor.

5) Look for the modem name:"ZTE MF626" and erase the comments, the ( # ) and the ( ; ), Until it looks something like this:

ZTE MF628+ (tested version from Telia / Sweden)

DefaultVendor= 0x19d2
DefaultProduct= 0x2000

TargetVendor= 0x19d2
TargetProduct= 0x0031

MessageEndpoint=0x01
MessageContent="55534243123456782000000080000c8501 0101180101010101000000000000"



6) Save and Quit.

7) Plug the modem, wait few seconds and execute "lsusb" in the terminal. Here one device must have the ID 19d2:2000.



8) Execute this in Terminal:

sudo /usr/sbin/usb_modeswitch -W -c /etc/usb_modeswitch.conf

With this we change the usb mode so the system recognize it as a modem. Do "lsusb" again, it has changed to ID 19d2:0031



10) Now it should be recognized as a modem...and we can define an archive in order to make this device recognizable by Network Manager, for this we write in terminal:

sudo gedit /usr/share/hal/fdi/information/20thirdparty/20-zte-mf626.fdi

This will open a blank archive and in it we write:

<!-- -*- SGML -*- -->
<deviceinfo version="0.2">
<device>
<!-- ZTE MF626 HSDPA USB Modem -->
<match key="@info.parent:usb.vendor_id" int="0x19d2">
<match key="@info.parent:usb.product_id" int="0x0031">
<match key="@info.parent:usb.interface.number" int="3">
<append key="modem.command_sets" type="strlist">GSM-07.07</append>
<append key="modem.command_sets" type="strlist">GSM-07.05</append>
<append key="info.capabilities" type="strlist">modem</append>
</match>
</match>
</match>
</device>
</deviceinfo>

Then Save and Quit

11) Now it should be seen in network connections as a new connection.

In the original page in spanish http://www.taringa.net/posts/linux/2...ZTE-mf626.html by MOZZart, it has other commands that for this ubuntu release I found unnecessary.

In my country and provider it's necessary to do some configuration in the network manager.
I have to do Edit Conections -> (in english could be something like) Mobile Broadband -> Add...and than select the mobile provider...

Reboot and than it will maybe () work fine...
any corrections and suggestions are welcome...

P.S.:I still don't find a way to automatize all the process, anytime I want to enter the internet I have to do: "sudo /usr/sbin/usb_modeswitch -W -c /etc/usb_modeswitch.conf"...anyone that knows a way I'll appreciate...

And this is is in jaunty!? i'm only asking because, many have troubles using usb_modeswitch in jaunty.

[Unkuiri]

Yeah, it worked for me in Jaunty...I tried many tutorials but the only one that worked is this one...

P.S.: I'm a newby in Ubuntu, maybe i'm making something wrong, if it happens please forgive me...

[loell]

ah great , i was only asking because some have this error

https://answers.launchpad.net/ubuntu...question/65281

but if it went just fine, then that's goog news

[Unkuiri]

I had that same error, as I know the usbserial module doesn't work on Jaunty and because of that I did a thing that a user said in other forum, I've edited the file "menu.lst" located in /boot/grub/ and added a line customized entry, copied the part that says:

title Ubuntu 9.04, kernel 2.6.28-11-generic
uuid 8a94291a-08f2-40dc-ac28-240589d74efc
kernel /boot/vmlinuz-2.6.28-11-generic root=UUID=8a94291a-08f2-40dc-ac28-240589d74efc ro locale=pt_PT quiet splash
initrd /boot/initrd.img-2.6.28-11-generic
quiet

and altered the new one to look like this:

title Ubuntu 9.04, kernel 2.6.28-11-generic custom
uuid 8a94291a-08f2-40dc-ac28-240589d74efc
kernel /boot/vmlinuz-2.6.28-11-generic root=UUID=8a94291a-08f2-40dc-ac28-240589d74efc ro locale=pt_PT quiet splash usbserial.vendor=0x19d2 usbserial.product=0x0031
initrd /boot/initrd.img-2.6.28-11-generic
quiet

I've altered the first line adding "custom"(this is only to know what boot option is)
and added: "usbserial.vendor=0x19d2 usbserial.product=0x0031" (this is for my case, for the modem cited at the top)

and then I booted from that new option...but when I tried to plug the modem and make it work it didn't work and then I tried again to boot normally from the normal option (not custom) and voilá it's working...Thats the reason I didn't say it in the "How-to"...do you think it's important to say that?

[loell]

Thats the reason I didn't say it in the "How-to"...do you think it's important to say that?

yeah.. but you already just said it, so it's fine.

Hi Unkuiri,
if above still exists, you can add a .rule file (as user JimmyI suggests with post #4 of http://ubuntuforums.org/showthread.php?t=1065934).

For your case you could create the file from terminal:
sudo gedit /etc/udev/rules.d/90-zte.rules

copy the following lines into gedit window:

ACTION!="add", GOTO="ZTE_End"

SUBSYSTEM=="usb", SYSFS{idProduct}=="2000", SYSFS{idVendor}=="19d2", GOTO="ZTE_ZeroCD"

LABEL="ZTE_ZeroCD"
RUN+="/usr/sbin/usb_modeswitch -W -c /etc/usb_modeswitch.conf"

LABEL="ZTE_End"

Save, Exit and reboot.

If all are OK, when you attach the modem (19d2:2000) the usb_modeswitch will run automatically changing to "modem state" (19d2:0031). As you are running the usbserial at boot, you don't need the "usbserial" part of above link.

Regards,
George

Hi guys,

I just want to ask those of you that have succeeded in getting the modem to work are you happy with it?

I read somewhere else that people are experiencing modem hangs after ~1hr of use, so do you get these too or it works reliably?

I am looking for a 3g modem to buy with Linux support #1 criteria on the list so this will be useful info.

Best regards,
Rado

Hi, For me works fine the only problem that I'm experiencing sometimes is that I have to unplug and re-plug for it to work, but all the remaining things work fine and is faster than windows for example......good luck for your search...

[Unkuiri]

Thanks GeorgeVita, What you said worked just fine......now it's just plug and play.....
