I have a GSM USB broadband modem which works nearly perfect in ubuntu natty, with one exception:

If I just boot the computer and log into the system no network connection is there and I am not able to connect with the network manager applet.

If i plug out the modem, plug it again into USB, everything works.

I can even plugout the modem before logging in, plug it in again, and then login. The connection will be there. Without replugging it will not.

This is part of dmesg:
The full dmesg can be found in the launchpad bugtracker

I suspect that usb-modeswitch triggers "USB Serial support registered for GSM modem (1-port)", but only after bootup.
