The lsusb listing shows that your dongle is supported by the option driver in kernel 3.13 which Ubuntu 14.04 is built on.
The problem is most likely a usb controller driver error, can you please test on a USB 2.0 port or with a USB 2.0 hub connected between dongle and your computers USB 3.0 port. The option driver could not bind because it could not read the attributes from the dongle, the same error that ModemManager complains about: "Jul 3 23:44:32 ModemManager[812]: <warn> (ttyUSB0): port attributes not fully set" -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1337542 Title: huawei e5372 not identified To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/usb-modeswitch/+bug/1337542/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
