ModemManager and e160

[Georg Grabler <georg grabler net>]

Dear .. all :-).

I've been using Network Manager (KNetworkManager) for quite some time now. Due to a problem with my huawei e220 (instability), I got myself a huawei e160.

Lately I installed networkmanager 0.8 and modemmanager 0.3. Since that, my modem is still found, but it seems as if it's not initialized properly. I can activate it / connect, but activating the state changes to connecting (Activating), but immediately (1 second to five seconds?) switches back to a state as if i never tried to connect / as if it couldn't get a connection.

Note: With the e220 it works properly, so I think it's probably some kind of initialization problem (in modemmanager?). If I try it with wvdial, it works fine.

The modem gets in an enough unusable state, that I can't connect at all anymore (not with wvdial or with networkmanager). I've tried both, KNetworkManager and gnome networkmanager applet.

Is there any way to backtrace it properly / provide help on this? I've tried making a bug report, but for some reason the gnome bugtracker won't send me my activation e-mail (grml).

Output I could get:

NetworkManager: <info>  Activation (ttyUSB0) starting connection 'bob.at'
