Unfortunately, you may be on your own then. Huawei software installs its own
mode switching program, regardless of what is present on the system. It may
switch the stick to a mode which is unsuitable for Network Manager (Huawei
modems have more than two different modes).
You can try to find this
No official ubuntu package, updated stick version. It's just weird that
i worked before and after upgrade and not on a fresh install.

So, did you install Mobile Partner from the stick or is there an
official Ubuntu package ?

Yup it's the same sequence and apparently the devices are recognized as
they should be but network-manager and Mobile Partner don't . And before
anyone says that the USB modem is broken, it works in Windows 7
including Mobile Partner for Windows.
One interesting thing though: if you uninstall Mobi
Hmm, it looks like your device has in fact switched to modem mode ...
It's not unusual for some devices to provide their "install storage"
again after the mode switching. I'm just wondering which program or
event is responsible for the switch.
In the dmesg output the mode switch process will show
[ 2729.139786] USB Serial support registered for GSM modem (1-port)
[ 2729.140454] usbcore: registered new interface driver option
[ 2729.140461] option: v0.7.2:USB Driver for GSM modems
dmesg results(end section):
If you compare the current log with this directory listing and the path
that udev provides (4-4:1.0) does not exist, then the hotplug system may
be to blame.
Could you post the end (starting from "new USB device") of the output
from the "dmesg" command, right after plugging the stick in ?

Can you check for the directory mentioned in the log (while stick

What's the content of "/sys/bus/usb/devices" ?

This is not a problem with modem-manager. It looks like the device was
not mode-switched properly.
Please enable logging of usb_modeswitch; to do this, edit
"/etc/usb_modeswitch.conf". It tells you about the log destiantion.
** Package changed: modemmanager (Ubuntu) => usb-modeswitch (Ubuntu)
