ZTE MF622 USB Modem Under Linux

Here’s the udev script that does the job:

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

# Is this the ZeroCD device?
SUBSYSTEM=="usb", SYSFS{idProduct}=="2000",
SYSFS{idVendor}=="19d2", GOTO="ZTE_ZeroCD"

# Is this the actual modem?
SUBSYSTEM=="usb", SYSFS{idProduct}=="0001",
SYSFS{idVendor}=="19d2", GOTO="ZTE_Modem"

LABEL="ZTE_ZeroCD"
# This is the ZeroCD part of the card, remove
# the usb_storage kernel module so
# it does not get treated like a storage device
RUN+="/sbin/rmmod usb_storage"

LABEL="ZTE_Modem"
# This is the Modem part of the card, let's
# load usbserial with the correct vendor
# and product ID's so we get our usb serial devices
RUN+="/sbin/modprobe usbserial vendor=0x19d2 product=0x0001",
# Make users belonging to the dialout group
# able to use the usb serial devices.
MODE="660", GROUP="dialout"

LABEL="ZTE_End"

Save this file as /etc/udev.d/15-zte-mf622.rules for example(this path is a good one under (K)Ubuntu).

The next time you plug-in the modem, at first, the usb_storage module get’s removed. After a few seconds, since the modem is not being handled like a storage device, it’ll switch to the modem configuration. At this stage we tell udev to load the usbserial kernel module with the vendor and product id’s and you’ll get 3 ttyUSB devices. The /dev/ttyUSB0 will be the one you should use to make a connection.

You can now point ppp or wvdial to that device a start the connection, or, you might also want to check UMTSmon, this is an application suited for these kind of modems.

Hi, Thanks alot, you are a saviour! Dead simple just remember to reboot once you’ve placed the file in the system to make it all work!

To Patrik: Sorry, don’t know what else you should do regarding umtsmon, perhaps contact the developer?

Hi! I have big problem with mounting external usb storage devices like HDD or my PSP. It loads without your script but when i copy it to /etc/udev/rules.d/ it’s stopping them from mounting. Do you have any solution?

Comment by Maciej Szpakowski — Mar 10, 2008 3:55:26 PM | # - re

I’m trying to find a solution for this myself. For now I’ve been connecting the modem and then hashing out the line in the script: RUN+=”/sbin/rmmod usb_storage” Then running: # udevcontrol reload_rules This stops it killing usb_storage after the modem’s already connected. Hope that helps, and hopefully I can find some time for something neater. Dave

The problem with removing “usb_storage” is that it affects all devices. If you use USB_ModeSwitch with the flag “DetachStorageOnly” the mode switching works too, but all other USB storage devices (disks, sticks etc.) continue to work. There is an entry for the ZTE MF622 in the config file now.

Just a simple answer to the usb-storage not working problem.I set up a directory in the root tree called udv-rls and copied the mf622 ruleinto there. I also put a sub-directory called bckup and copied all the rules from udev into that for security. I then wrote a small shell script: : #!/bin/bash cp -v /udv-rls/15-zte-mf622.rules /etc/udev/rules.d/ udevcontrol reload_rules # end of script. I saved it in /bin as “3up” That then loaded the rule. I made sure that there were no usb_storage devices in the usb ports, and then plugged in the mf622 dongle and waited for it sort itself out. After it had produced the /dev/ttyusb0 I then ran another script I called /bin/usf #!/bin/bash rm -v -f /etc/udev/rules.d/15-zte-mf622.rules udevcontrol reload_rules #end of script (I found the “force” switch necessary) I could then plug in the usb-storages device(s) at will. The shell scripts have to be run as root from a shell terminal. I use opensuse10.3 I also expect it to work on mandriva 2007.

Hi guys, You Linux users are a more adaptive lot than us Windozers. I also have a ZTE MF622 and it works fine on my XP laptop. But I truly hate the official software and would like to automate the connection process. Their app auto-starts when the device is plugged in and it does some magic to initialize the modem. Their ‘connect’ button creates a Dial-Up Networking profile and launches that. With their software loaded, but disconnected, I can connect manually with a profile of my own. However, when I close their ghastly software the modem light goes from green to red and the DUN profile complains that the modem has gone, although it is still available in the devices list and can still be quieried with the built-in modem diagnostic util. So my question is this… what black magic have you guys discovered to initialize the modem, check the usim, connect to the 3g network, etc. All of that seems to be done by the nasty nasty win app, and the modem isn’t ready to connect with (although does exist as a queryable modem) until then. I’m asking you guys not because I expect you to care but coz I think you already understand far more about this device than I do. Thanks in advance for any assistance you can offer me. Cheers, Peter C

This brings us to the linux “problem” when using these modems. The thing is, software/hardware creators care more to have a Supported by Window$ logo than by making good and simple software. In this modem case(and other modems like this one), they tried to make it as annoying as Window$ itself is, “the user shouldn’t have to do anything”, so, the modem contains 2 different hardwares, an storage hardware like a pen-drive(so that it also provides the windows software to use the modem) and the modem. What we linux users do(and what you want to also do) is make the modem “switch” from pen-drive to the actual modem, that’s what the provided window$ software does besides some other crappy stuff ;) From my point of view, you’re stuck with that software but what you might try to search for is, window$ software like usb_modeswitch(http://www.draisberghof.de/usb_modeswitch/) or UMTSmon(http://umtsmon.sourceforge.net/) both for linux ;) The idea is, you have to be able to make the modem switch from pen-drive to the actual modem. You might want to try to go to your control panel -> system hardware and when you plug the modem you’ll briefly see a new usb storage device or a new cd-rom like device, by right clicking that device you have the option to ignore that device. What happens is that after a few seconds, if the pen-drive or cd-rom driver isn’t used, the fake-modem auto-switches to the actual modem, though, if you have it’s software installed, you probably won’t be able to do this. Note that I won’t be held responsible for anything you do on your Window$! ;)

Comment by s0undt3ch — Oct 13, 2008 3:05:41 AM | # - re
- Thanks s0undt3ch. I get the pen-drive vs. modem debate. I’ve watched the hardware devices come and go as it is plugged in. I’ve not yet been able to stop their hideous app from launching when it’s inserted so I don’t know whether their app does the switching or something else - probably their app. I suspect that if I ever do manage to disable it then I will need to do the switching myself, as you suggested. As it is I am stuck on the next step which is how to make the modem connect to the 3g network. That is something which their software does when it starts. You cannot “connect” until it’s ready for you. The bummer is that it closes it all down again when the software is closed. If I leave theirs running, but not connected, then I have a working 3G modem to play with via terminal, or through DUN. But close their software and it all falls apart again :-( I think I’m on my way to sorting that out by initializing it via the NMEA port, as I subsequently posted about. I suppose I should count myself lucky that, as a signed up Windozer (I’ve got a pointy hat with a big “D” on it), I don’t *have* to get this working. I pity you guys who are so poorly supported by the manufacturers and have to resort to the cunning hacks. At least you learn stuff though. I’ve had my hand held for so long I’m really struggling here! Thanks for your advice. If I crack this then I will post back - you never know, it may even help one of your Linuxer mates :-) Cheers, Pete.

Hi again, Just did some more sniffing and it seems to be the exchange on the NMEA COM port that initializes the device. I logged a number of start ups and it doesn’t seem to be the same twice, so I might need to spend some time looking into this NMEA business (it’s all new to me). Tried replaying a couple of the sequences and I still don’t get a green light. However, I’m hopeful that this will eventually yield a working modem, ready to use with Windows Dial-Up Networking. To help me follow the various Linux instructions that I’ve found perhaps you can tell me what utility/app you guys use to init the device? Presumably your Linux app does the same thing on the NMEA port? Windozers don’t seem to hack about with the same gusto that Linuxers do. Maybe I’m batting for the wrong team (but not in a sexual way)! Cheers again, Pete

please be aware that the udev script here will break aspects of your system (and not work for the ZTE) if you are using usb-storage or usb-serial for anything else (such as a USB pen drive or USB serial port adapter). There is a program “usb-modeswitch” that can flip the ZTE devices over to serial mode without having to forcefully remove or insert modules; however, it seems since at least 2.6.26 the device flips over of it’s own accord without manual intervention (on Debian Lenny at least).

Comment by Jon — Apr 7, 2009 9:10:56 PM | # - re

Yes, you are right, it breaks storage support and at least for me, I now don’t need this script since Kubuntu 8.10 flips my modem, at least, last time I tried it ;)

Hi there

ZTE MF636 using Slackware, with kernel 2.6.30.5

This is my zte-mf636-beta.rules (I use the option module which is reputed to use a higher speed)

ACTION!=”add”, GOTO=”ZTE_End”

Is this the ZeroCD device?
SUBSYSTEM==”usb”, SYSFS{idProduct}==”2000″,
SYSFS{idVendor}==”19d2”, GOTO=”ZTE_ZeroCD”

Is this the actual modem?
SUBSYSTEM==”usb”, SYSFS{idProduct}==”0031″,
SYSFS{idVendor}==”19d2”, GOTO=”ZTE_Modem”

LABEL=”ZTE_ZeroCD”

This is the ZeroCD part of the card, remove
the usb_storage kernel module so
it does not get treated like a storage device
RUN+=”/usr/bin/eject /dev/sr0”

LABEL=”ZTE_Modem”

This is the Modem part of the card, let’s
load usbserial with the correct vendor
and product ID’s so we get our usb serial devices RUN+=”/sbin/modprobe usbserial vendor=0x19d2 product=0x0031”,
Make users belonging to the dialout group
