Unfortunately, you may be on your own then. Huawei software installs its own mode switching program, regardless of what is present on the system. It may switch the stick to a mode which is unsuitable for Network Manager (Huawei modems have more than two different modes).
You can try to find this mode switching program and disable it. See if it makes a difference to let usb_modeswitch handle the stick.

In any case, this is not an Ubuntu bug.
