Status changed to 'Confirmed' because the bug affects multiple users.

My exact situation concerns another usb modem from ZTE - MF110

I wanted to mention that it worked pretty well under KUbuntu 15.04 (NetworkManager 0.9.7).

Furthermore, after trying the first connect sequence the device cannot be polled for signal monitoring.

At least, does anyone have a clue how to override the usb_modeswitch.d so I can utilise the device like before ?

I am not the single one affected and I can provide, if requested, some info/logs about another ZTE usb modem model that is experiencing the same problems after upgrading to 15.10

Regards,

Ștefan

Is there more than one modem connected? The above logs, from comment #7 seem to indicate that the modem is correctly found, and succesfully registered to the network. Does it show up in the network manager indicator?

Hi. My modem is ZTE MF 180S. The modem identifies as CR-ROM but it doesn't switches in modem mode.
However the modem works correctly on my second laptop (Dell Vostro 1015). My first laptop (Dell Inspiron 7548) has not an ethernet port and my second laptop has it. I used Ubuntu 14.04, Ubuntu 16.04 and Linux Mint 17.2 (x64).

PS.
Dell Vostro 1015: Ubuntu 16.04 x64, bios.
Dell Inspiron 7548: Ubuntu 16.04 x64, uefi (secure boot is off).

PPS. Sorry for my bad english.
