Mobile broadband unavailable in nm-applet

[karaluh]

As in summary. It also doesn't show up in Plasma Network Manager widget. lsusb lists the modem, ls /dev shows ttyUSB ports, nmcli confirms wwan is enabled.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately, we cannot work on this bug because your description didn't include enough information. You may find it helpful to read "How to report bugs effectively" http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem.

We have instructions on debugging some types of problems at http://wiki.ubuntu.com/DebuggingProcedures

At a minimum, we need:
1. the specific steps or actions you took that caused you to encounter the problem,
2. the behavior you expected, and
3. the behavior you actually encountered (in as much detail as possible).
Thanks!

>. the specific steps or actions you took that caused you to encounter the problem,

1. Plug USB broadband modem into USB port

> the behavior you expected, and

1. New mobile broadband interface becomes available in NM widget
2. Plasma Device notifier detects integrated pseudo CD flash memory with windows drivers

> the behavior you actually encountered (in as much detail as possible).

1. Plasma network manager widget doesn't show the mobile broadband device, so I'm unable to connect with it
2. Device notifier doesn't notify me about new CD

The same behaviour can be observed in Gnome's nm-applett. I've tried two different modems and almost all available USB ports to no avail.
