Yes you do need this usb switch thing.

I only posted this yesterday, it really shouldn't be hard to find. I know the post relates to Helena, but it should work for Gloria or any other version too, and unlike the version you probably downloaded, it requires no configuration whatsoever.

BTW to install it you download, then double click the file - you may even be given the option to install it when you opt to download. Whichever, it shouldn't be too difficult to accomplish.

Am I missing something here? The link to my earlier post contains another link to the site from which you can download usb_modeswitch - just scroll down to the bottom of the page and you will see a table with various processor architectures, click on the one that matches your computer and you will be taken to another screen where you choose a mirror - usually the closest to where you live, but it is such a small file it wont matter much which one you choose. A box will pop up asking you what you want to do with the file (install or save). In this case you choose save. Then move it from your girlfriends pc to yours and double click on it to execute the file and you should be good to go.

The ZTE 626 is listed as a supported modem so it should work for you although I must admit that I haven't tried the latest version on Gloria (because version 1.0.2 works for me there) but version 1.0.5 is a BIG improvement over 1.0.2 as it requires no work to configure it after install.

Here is the link again:

First let me say that if you are having to type anything at all to install the package then you have downloaded the wrong program. You have downloaded the tarball and you should have downloaded the .deb file - I did explain very precisely how to find it on the site I linked to. So you will have to start again. I have been using Linux off and on for 10 years, and even after that time my success rate in installing from tarballs is about 1 in 20, your chances will be to all intents and purposes zero!

However having said that I have to report that I am now having difficulities with my ZTE modem as well (although that is on Mint 8 not Mint 7). When you get the correct file (the file extension is .deb not .tar.gz) all you have to do is to click on the thing to install it, then just plug in the modem wait for it to be detected (about 30-40 seconds with my modem on Mint 7) and then connect with the gnome network manager.

Trouble is at the moment that doesn't appear to be happening for me either - 3 days ago it was working. :?: :?:

EDIT. Another thing to try once you have usb_modeswitch installed (assuming it doesn't work that is) Is to plug the modem in before you start the computer - I just noticed that this works for me with both Ubuntu 9.10 and Mint 8. Not a very elegant solution but it works till someone figures out what has gone wrong here.

EDIT2. I don't know if you have been reading my other post on this subject, just in case not I will repeat it here. I now have my modem working on Mint8 and Ubuntu 9.10. In order to achieve this I had to downgrade usb_modeswitch back to version 1.0.2 although I also installed a new kernel so that might have made a difference as well. So I am now not sure if usb_modeswitch 1.0.5 is as good as I thought it was initially. If you can get it working then I would use it as it requires no configuration. 1.0.2 does require configuration (though not much) but may work better for you. If you want a link to version 1.0.2 then this is it:

http://packages.ubuntu.com/karmic/usb-modeswitch

and you download from the box at the bottom not the one at the right hand side.

That is a ubuntu package because I couldn't find the link for the Mint package but they will almost certainly be the same.

Version 1.0.2 won't work until you configure it - that is why I wanted you to try 1.0.5 first, anyway this is how to configure 1.0.2.
EDIT. I have lately had problems with version 1.0.5 and have reverted to 1.0.2 exclusively)

First hit Alt/F2 on the keyboard then type

Code: Select all
gksu gedit


Enter your password and your text editor will open. From the gedit 'open' menu navigate to etc/usb_modeswitch.conf and open it. (If for some reason usb_modeswitch.conf doesn't exist you can get it from here http://www.draisberghof.de/usb_modeswitch/ save it as a file and put it into /etc) Scroll down to the section for your modem which will look like this:

Code: Select all
# ZTE MF628+ (tested version from Telia / Sweden)
# ZTE MF626
#
# Contributor: Joakim Wennergren

;DefaultVendor=  0x19d2
;DefaultProduct= 0x2000

;TargetVendor=   0x19d2
;TargetProduct=  0x0031

;MessageEndpoint=0x01
;MessageContent="55534243123456782000000080000c85010101180101010101000000000000"

# if that command doesn't work, try the other ("eject")
;MessageContent="5553424312345678000000000000061b000000030000000000000000000000"



Alter it to make it look like this:


Code: Select all
# ZTE MF628+ (tested version from Telia / Sweden)
# ZTE MF626
#
# Contributor: Joakim Wennergren

DefaultVendor=  0x19d2
DefaultProduct= 0x2000

TargetVendor=   0x19d2
TargetProduct=  0x0031

MessageEndpoint=0x01
MessageContent="55534243123456782000000080000c85010101180101010101000000000000"

# if that command doesn't work, try the other ("eject")
;MessageContent="5553424312345678000000000000061b000000030000000000000000000000"



ie I have removed six semicolons -that is all.

Save the file. Remove the modem, reboot then plug in the modem and wait for about 60 secs.

Open a terminal and run this command:

Code: Select all
ls /dev/ttyU*


It should return something like this:

Code: Select all
/dev/ttyUSB0  /dev/ttyUSB1  /dev/ttyUSB2


If it says 'not found' or something similar it hasn't worked so go back to the usb_modeswitch.conf remove the semicolon from this line:

Code: Select all
;MessageContent="5553424312345678000000000000061b000000030000000000000000000000"


and place a semicolon in front of this line:

Code: Select all
MessageContent="55534243123456782000000080000c85010101180101010101000000000000"


Then unplug the modem. reboot, plug in again and wait again for switching to take place, then repeat the command

Code: Select all
ls /dev/ttyU*


If that doesn't return:
Code: Select all
/dev/ttyUSB0  /dev/ttyUSB1  /dev/ttyUSB2


Then I dunno :lol:
