[Thomas Klute <868034@xxxxxxxxxxxxxxxxxx>]

I've been using my E220 with wvdial since the upgrade to Oneiric,
attached is the configuration I use (except the PIN). I tried to
reproduce the "try to connect -> reset -> replug -> works with network-
manager" workaround with limited success (worked sometimes, but not
reliably).

I have some additional observations:

1. After plugging in the modem, I need to wait until usb_modeswitch is
done before starting wvdial or it won't work. Network-manager recognizes
the modem before the switch is complete and asks for the PIN, if I
provide it the device won't work.

2. wvdial does not work after a failed network-manager connection
attempt, no matter if with or without reset. I have to replug the
device.

3. Network-manager does not recognize the modem after reset without
replugging, even though the kernel log shows the disconnect/connect
events.
