It seems it's a bug into: /lib/udev/rules.d/40-usb_modeswitch.rules
By editing the relevant entry from ATTRS{idVendor}=="1ee8", ATTRS{idProduct}=="0012", RUN+="usb_modeswitch '%b/%k'" to ATTRS{idVendor}=="1ee8", ATTRS{idProduct}=="0012", RUN+="/sbin/modprobe option" I got the "Mobile Broadband" tab enabled. The mobile broadband is not working, anyway. -- network configuration for mobile broadband is not possible any more https://bugs.launchpad.net/bugs/663942 You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to kdebase-runtime in ubuntu. -- kubuntu-bugs mailing list kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
