Comment 3 for bug 891307

Hello Josua,

Strange, I didn't find it in 40-usb_modeswitch.rules. I only found in the 77-mm-zte-port-types.rules, which was not enough, for me, for nm detect it as a wwan modem. See:

/lib/udev/rules.d # grep 0031 *
69-xserver-xorg-input-wacom.rules:ATTRS{idVendor}=="056a", ATTRS{idProduct}=="0031", SYMLINK+="input/tablet-pl500"
77-mm-zte-port-types.rules:ATTRS{idProduct}=="0031", ENV{.MM_USBIFNUM}=="03", ENV{ID_MM_ZTE_PORT_TYPE_MODEM}="1"
77-mm-zte-port-types.rules:ATTRS{idProduct}=="0031", ENV{.MM_USBIFNUM}=="01", ENV{ID_MM_ZTE_PORT_TYPE_AUX}="1"

 /lib/udev/rules.d # grep 19d2 * | grep 00 | sort -n

I guess 77-mm-zte-port-types.rules does not call usb_modeswitch, which seems to be mandatory for NM. The 3g is not mine but from my brother. If needed, I can send the dmesg info in the next weekend. Anyway, if most of models are in 40-usb_modeswitch.rules and it only worked after I added the entry, the vendor/product on it might be necessary.

Please, correct me if I'm wrong. I'm not expert in 3g modems.
