I have this as well, with both my Option 3G Datacard, and a borrowed
Novatel 740. After killing the PPP connection, the virtual USB serial
port simulated by the card is not responsive any more, AT commands are
ignored.
Sometimes, it is sufficient to unload and reload the usbserial module,
but usually, it is necessary to pull the card and to dial in again
afterwards. This is becoming a major nuisance.
Greetings
