Comment 41 for bug 875441

Still nothing I've disabled PIN, restart modemmanager and network-manager but nothing start the modem

Samsung RC530
Ubuntu Precise 12.04 - amd64 - 3.5.0-030500-generic

Bus 001 Device 023: ID 19d2:0031 ZTE WCDMA Technologies MSM MF110/MF627/MF636

usb_modeswitch corrrectly switch from 19d2:2000 to 19d2:0031 as in defined in /lib/udev/rules.d/40-usb_modeswitch.rules

modemmanager works sometimes (after lots of plugin plugout) usualy after a SEGFAULT

checking /lib/udev/rules.d/77-mm-zte-port-types.rules
  ATTRS{idProduct}=="0031", ENV{.MM_USBIFNUM}=="03", ENV{ID_MM_ZTE_PORT_TYPE_MODEM}="1"
  ATTRS{idProduct}=="0031", ENV{.MM_USBIFNUM}=="01", ENV{ID_MM_ZTE_PORT_TYPE_AUX}="1"
it seams correct to me the error must be some were else.
