usb_modeswitch has done all it should do , switched the dongle from initial mode (cd-rom only) to modem mode ( usb id 12d1:1506 ).
The syslog clearly indicates a NetworkManager error so the bug report should go there and mot be filed as a usb_modeswitch bug.
usb_modeswitch is not the NetworkManager!

Even my modem stopped working after latest update. Removed ofono and installed modemmanager and modem is working again.

Modem can function HiLink, but in the firmware MTS (Russian operator) was no such possibility.
I flashed modem on the universal firmware and installed WebUI.
Now the device has other PID and VID:
Bus 003 Device 005: ID 12d1:14dc Huawei Technologies Co., Ltd.
Connects and works fine automatically, only had to upgrade the package usb-modeswitch on repository of Debian Sid.
Problem solved.

Confirm the problem persists after the update packages usb-modeswitch, see bug-report https://bugs.launchpad.net/ubuntu/+source/usb-modeswitch/+bug/1354823, comment #11

The developer was created patch all who have problems (with the updated usb-modeswitch) with Huawei E3372, Huawei E3531 write there - https://bugs.freedesktop.org/show_bug.cgi?id=86658#add_comment

I am seeing something completely different and for me the issue is with usb_modeswitch first:

This is what I see when I plug mine in: https://gist.github.com/xanview/3a37e6eb0cf24a12908b

The key lines are:

Jan 28 16:19:23 TimeBox systemd[1]: Starting USB_ModeSwitch...
Jan 28 16:19:23 TimeBox systemd[1]: usb_modeswitch@1-1.5-1-1.5:1.0.service: main process exited, code=exited, status=1/FAILURE

It seems Ubuntu is trying to do the wrong thing, it is trying to do systemctl start usb_modeswitch@1-1.5-1-1.5:1.0 when in reality the command should be:

$ systemctl start usb_modeswitch@1-1.5:1.0

When I run the correct command, I see this in syslog:

Jan 28 16:34:05 TimeBox systemd[1]: Starting USB_ModeSwitch...
Jan 28 16:34:05 TimeBox usb_modeswitch_dispatcher[10502]: Could not read attribute: No such file or directory

Jan 28 16:34:15 TimeBox systemd[1]: Started USB_ModeSwitch.

So seems this is an unsupported device still? (I'm on Ubuntu 15.04 Vivid)
