I have a Huawei E3372 modem, and I'm also having some issues, even though I found a way to connect.
At first the modem was not switching modes (stuck in 12d1:1f01), and lsusb output was: Bus 003 Device 039: ID 12d1:1f01 Huawei Technologies Co., Ltd. At this point everytime I plugged the modem the blue led stayed on (connected), but it wasn't recognized, and I couldn't use it or find it in Network Manager whatsoever. After looking around on the internet, I found this command to switch modes which worked for me: usb_modeswitch -J -v 0x12d1 -p 0x1f01 After issuing this command NetworkManager popup saying new ethernet connection was available and I could connect. Still, the modem was not recognized, but working. The output of lsusb was: Bus 003 Device 039: ID 12d1:14dc Huawei Technologies Co., Ltd. Playing around with usb_modeswitch found that switching to 0x1001 the blue led started to blink instead of being always on, and after a few seconds the modem was recognized, I tried to setup a broadband connection but I couldn't connect. Now lsusb was printing: Bus 003 Device 039: ID 12d1:155f Huawei Technologies Co., Ltd. I'm attaching the system log since I plug the modem till connection attempt finally times out. I can use the modem, but not 'dialing' I would say. Hope it helps, let me know if I can provide you with some more information. ** Attachment added: "syslog modem detection" https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1507957/+attachment/4660874/+files/syslog.txt -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1507957 Title: Huawei E3372 LTE modem on 15.10 works only when connecting via wvdial and not network-manager Status in network-manager package in Ubuntu: Confirmed Bug description: If you plug the modem first time after booting, it cannot connect.
