Comment 3 for bug 893238

The latest one usb_modeswitch data package release (20120531) partially solves the problem. With it the modem is swithed to pseudo-ethernet device (cdc_ether), and NetworkManager is able to conect.

But there is another problem: ModemManager uses static IP configuration for this modem, but it should use DHCP instead. Without DCHP request the connection is not initiated and no internet server could be reached, though NetworkManager says, the connection is established.
