@ Saurabh Sharma 12d1:1506 is a usb id for E3531s after it has been mode switched so usb_modeswitch has done what it should do. I think your problem is either linux driver related or NetworkManager related so please provide the output from: lsusb -v -d 12d1:1506
It will show how the interfaces are intended to be used and which driver(s) should be used. You can also do: cat /proc/bus/usb/devices which will show which drivers have already bound to the interfaces. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1308895 Title: Please merge usb-modeswitch from Debian unstable - Huawei E3531 does not automatically switches to modem mode (no udev rules for this modem in Ubuntu's /lib/udev/rules.d) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/usb-modeswitch/+bug/1308895/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
