This "modem key" worked out of the box for me in ubuntu 15.10. However now, in 16.04, the "usb mode switch" is not done automatically (both is the modem is plugged at boot or after).
I suppose it's an udev regression. So, when the "key" is plugged (lsusb): Bus 002 Device 010: ID 12d1:1f01 Huawei Technologies Co., Ltd. E353/E3131 (Mass storage mode) $ usb_modeswitch -J -v 0x12d1 -p 0x1f01 => Bus 002 Device 011: ID 12d1:14dc Huawei Technologies Co., Ltd. And now the device work as expected and can be choosed in network manager. So there is no kernel problem for me. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1527914 Title: Huawei E3372 is not detected and cannot be used Status in linux package in Ubuntu: Incomplete Bug description: It does appear in lsb_usb, but networkmanager doesn't react to it or give me option to connect.
