Please enable logging of usb_modeswitch; to do this, edit "/etc/usb_modeswitch.conf". It tells you about the log destiantion. ** Package changed: modemmanager (Ubuntu) => usb-modeswitch (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/991680 Title: Huawei E220 and E1550 can't connect on Ubuntu 12.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/usb-modeswitch/+bug/991680/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
