Can't connect with Sony Ericsson MD400

[Jonas Skubic]

Binary package hint: modemmanager

My Sony Ericsson MD400 HSPA USB modem stopped working after I upgraded to karmic. It worked fine in jaunty.

I've installed the latest version from the PPA:

ii modemmanager 0.2.git.20091201t192528.f715e0d-0ubu D-Bus service for managing modems
ii network-manager 0.8~a~git.20091203t185502.9c37194-0u network management framework daemon

mm-test.py throws an exception:

I do not know if it's the same bug, I think so.

after upgrading from Ubuntu 9.04 to Ubuntu 9.10 (karmic) I can not connect to internet with Sony MD400.

 I installed usb_modeswitch 1.0.5, and it works:

Looking for target devices ...
 No devices in target mode or class found
Looking for default devices ...
 Found default devices (1)
 Found a default device NOT in target class mode

However I can not connect to the Internet with networkmanager or gnome-ppp. As i used.

the syslog generated by both programs are in attachment.

Thanks!

I'm runnig Ubuntu Karmic too, so I have the same problem, but found an ugly workaround:

First i use usb_modeswitch as stated in many places:

> sudo usb_modeswitch -v0x0fce -p0xd0e1 -O 1

Then I try to connect using wvdial, it doesn't work, but somehow it seems to initialize the MD400 (a blue lamp starts blinking)

> wvdial

I use the following /etc/wvdial.conf :
---START---
[Dialer Defaults]
Init1 = ATX3
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init3 = AT+CFUN=6
Init4 = AT+CGDCONT=1,"ip","internet.sonofon"
Phone = *99#
Modem Type = USB Modem
Baud = 460800
New PPPD = yes
Modem = /dev/ttyACM0
ISDN = 0
Password = ''
Username = ''
---END---

Note: Modem = /dev/ttyACM0 have to be changed to whatever your device is ttyACM1, ttyACM2,... or even ttyUSB0,... I don't what other part of the file might be important, it just worked for me.

After that the network manager can connect using the default settings.

Note: you have to run the two lines above every time you plug in the stick or restart the system.

As mentioned, I think the problem occurs somewhere in the initialization of the modem, but cant say where precisely, as this fix was more luck then something else...

System: EEE Pc 1000, Xubuntu Karmic, Sony Ericsson MD400

I tried it and it works, right now I am using wvdial. thanks.

Seems to be a udev issue, probably the same as bug #451787 (MD300)

I confirm the bug because 3 other people subscribed to it as affected.

Discovered in version: Karmic 9.10

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue that you reported is one that should be reproducible with the live environment of the Desktop CD of the development release - Lucid Lynx. It would help us greatly if you could test with it so we can work on getting it fixed in the next release of Ubuntu. You can find out more about the development release at http://www.ubuntu.com/testing/ . Thanks again and we appreciate your help.

Sergio: what makes you think that this is a udev issue? From the logs above, it looks like a device node exists in /dev ?

[Sergio Zanchetta (primes2h)]

@Scott
Bug #451787 is about a different model (MD300) of the Sony Ericsson HDSPA usb modem.
That bug is about a value in udev rule that change the way the modem is detected (as a modem or a storage device).
I guessed it could be a similar issue that in some way can interfere with the modem itself.

The bug seems to be present in both 10.04 and 10.10 alpa 3

Hi,

you just need usb-modeswitch and usb-modeswitch-data from maverick and it should just work (aka switch the device from storage to modem). The rest is out of scope from usb-modeswitch.
