It should be either 0154 or 0156, not both. Likely, you see it first as one PID and then as another one because it is mode-switched by usb_modeswitch; ModemManager should tag only the final VID/PID.

What's the PID of the device when ModemManager handles it? Is it 0x0154?

Could you get ModemManager debug logs like this?
http://www.freedesktop.org/wiki/Software/ModemManager/Debugging/

If you plug the modem in a Windows machine, do you get a "fake CD" drive? If so, could you get the contents and put them available for us somewhere?

1) ModemManager (mmcli) doesn't show product-ID info at all.


2) When the modem is plugged in, syslog shows PID 0x0154:

3) lsusb -v output shows PID 0x0156:

Aleksander,
I've tested using only one of the PIDs in /usr/lib/udev/rules.d/77-mm-zte-port-types.rules.

1) Using 0x0154: doesn't work (ERR: port attributes not fully set)
2) Using 0x0156: works alright!

Hence, the needed lines (192-193) in the .rules file are:

192 ATTRS{idVendor}=="19d2", ATTRS{idProduct}=="0156", ENV{.MM_USBIFNUM}=="02", ENV{ID_MM_ZTE_PORT_TYPE_MODEM}="1"
193 ATTRS{idVendor}=="19d2", ATTRS{idProduct}=="0156", ENV{.MM_USBIFNUM}=="01", ENV{ID_MM_ZTE_PORT_TYPE_AUX}="1"

The "port attributes not fully set" is totally unrelated...

You're seeing 0x154 in syslog and the 0x156 in lsusb because usb_modeswitch switched the modem in between. So, likely 0x156 is only enough in the port type rules.

Could you post the full output of lsusb -v for that device? Would like to confirm all the interface numbers available.

Ok, pushed fix at git master and the mm-1-4 branch, thanks.
