Yeah, check if ModemManager sees the device. NetworkManager uses ModemManager to talk to mobile broadband modems. If you're using MM >= 1.x, which you likely are, try listing modems with "mmcli -L". If you don't see it listed there, try to gather debug logs of ModemManager following these steps: http://www.freedesktop.org/wiki/Software/ModemManager/Debugging/ Also, if the tty is from a physical serial port (i.e. no USB), you'll likely need to tag the port in udev with the ID_MM_PLATFORM_DRIVER_PROBE flag as well. ModemManager doesn't automatically probe physical serial ports. BTW; this is the ModemManager specific mailing list, you may want to move the discussion there: http://lists.freedesktop.org/mailman/listinfo/modemmanager-devel -- Aleksander https://aleksander.es _______________________________________________ networkmanager-list mailing list [email protected] https://mail.gnome.org/mailman/listinfo/networkmanager-list
