ZTE MF622 USB 3G modem
 

Hi,

I have OS2008 and USB Host Mode configured and working.
I plugged in my ZTE HSDPA MF622 3G modem (trough a powered USB HUB) and this is an output of dmesg:

Is there any chance to put this modem working to access internet?

Re: ZTE MF622 USB 3G modem
 

If someone ports the UMTSMON project to maemo... who knows. I would appreciate it! so i could use my huawei E220 usb modem with my N800

Regards,

That would be really awesome.

Re: ZTE MF622 USB 3G modem
 

First:

I know nothing about the ZTE MF622 USB 3G Modem. I am evaluating the purchase of one of this modems and, as a Linux only user (inlcuding my internet tablets), I am validating if the device works with Linux, specially with the NIT N810.

Once said that. I found this link that states that removing the usb_storage module then, the device should switch itself to a modem mode and hence work correctly as a modem.

This is based on the fact that the ZTE is not an storage device.

Could some of you verify if this is also valid on the Internet Tablet (OS2008) when a ZTE MF622 is attached to its USB port. ?

I hope we can make the 3g Modem work as it will give even more life and usefulness to the NIT.

Comments are welcome.

Kind regards.

Here's a quick build. No idea if it works. It runs but I don't have a modem to try it on. Also in the kernel our N800 uses, the author says autodetection is broken.

Re: ZTE MF622 USB 3G modem
 

And for you ZTE owners, I haven't forgotten about you.

Here is a port of usb_modeswitch.
http://www.mediafire.com/?dhzegdkasns
The deb was hastily made, install with dpkg --force-all

And libusb:
http://www.mediafire.com/?lj4awrlcthm

Go to http://www.draisberghof.de/usb_modeswitch/ to set it up. You will need the usbserial module which can be found here:
http://www.internettablettalk.com/fo...ad.php?t=14877

ID's are here. http://blog.ufsoft.org/2007/11/30/zt...em-under-linux

EDIT: Here's a page in Spanish with ZTE info and usb_modeswitch:
http://oasis.dit.upm.es/~jantonio/personal/mf620/

remember to use insmod rather than modprobe and insmod the usbserial module from above, wherever you placed it.

Another page with a different method:

Re: ZTE MF622 USB 3G modem
 

I just saw that the Spanish tut needs comgt. Here is a binary I built. I can't compile wvdial.

Re: ZTE MF622 USB 3G modem
 

Hi people, I just logged in to share how I managed to make this damn thing work. It's not the best solution out there (yet), but I have to share it before I lose momentum and interest.

My modem is ZTE MF622 HSDPA Mobile Modem from THREE Mobile UK network. I have Debian Linux. Should work with Ubuntu and other derivatives without too much trouble.

I followed the instructions posted by zaurus6k on eeepc forum: http://forum.eeeuser.com/viewtopic.p...100536#p100536

So: check for usbserial module in your kernel (/boot/config-yourkernel or by zgrep /boot/initrd-yourkernel), go to step 4) if you have it

The difference is, in step 4) you give different parameters:

4)
sudo modprobe –r usbserial
sudo eject /dev/sda ( the cd with "Default OS" drivers, I prefer to unmount it first )
sudo modprobe usbserial vendor=0x19d2 product=0x0001 (this is the infamous MF622 modem )
sudo dmesg|grep –i ttyUSB (not necessary but makes sure the driver loaded correctly, you should see ttyUSB0 for example)
NOTE: as in "Default OS", when you run a control program, you need to wait about 30-60 seconds after ejecting CD before modem becomes available.
NOTE2: modprobe -r usbserial and modprobe usbserial vendor=0x19d2 product=0x0001 are possibly unnecessary. This should achieved by adding correct kernel parameter or compiling usbserial as a module and adding line "usbserial vendor=0x19d2 product=0x0001" to /etc/modules. Please, correct me if I am wrong.

Then you go setting up your favorite dialling program. I use wvdial. This again is something found on the internet ( http://ubuntuforums.org/archive/index.php/t-665332.html )
Contents of /etc/wvdial.conf, change owner to root and read access to anyone

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

Modem = /dev/ttyUSB0
Baud = 460800
ISDN = 0
Modem Type = Analog Modem
Init2 = ATZ
Init3 = ATE0 V1 &D2 &C1 S0=0 +IFC=2,2

Now, invoke wvdial and you have internet connection, that's utterly unusable.

Disconnect. For some strange reason the THREE assigns 4.2.2.4/3 as DNS. They DON'T work. "Default OS" shows WINS servers being used, this may be the hint to correct name resolution, but I have no idea about that.

I'm using OpenDNS for now, but they are slooooow. I'll try to find something faster later. This solution comes from http://gentoo-wiki.com/HARDWARE_HUAW...EM#DNS_problem

Edit /etc/resolv.conf, put those lines close to the top.
#Open DNS server
nameserver 208.67.222.222
nameserver 208.67.220.220

This propably won't work permanently (as resolv.conf is modified with each new connection), but I don't know where Debian hides his counterparts of gentoo's /etc/conf.d/net and /usr/ppp/peers/.

Now, I didn't go as far as making an udev script to automate this procedure. Everything is done manually.
Maybe one day I will go further with this, but now I have another things to work out. Hey! I went through patching and adding custom DSDT to my initrd! Forget kernel recompilation.

I hope this helps some people out there.

Re: ZTE MF622 USB 3G modem
 

i did some looking around and dont find..

if you dont have hotspots, where does the modem get connection?

you sposed to use your phone?

from separate service?

if i dont know, then i dont need it?

Re: ZTE MF622 USB 3G modem
 

It's an HSDPA modem. It connects to the nearest HSDPA base station. I don't know if it can fall back to GPRS or not, but I'd expect so.
