Public bug reported: I have a laptop with a mobile broadband device which only ever initialises on a reboot.
If I suspend to ram and then resume it fails to work. If I power the machine down and then cold boot it asks for the sim pin code which then also asks for the administrator password. However if I reboot the device initialises fine and connects immediately without any pin code nor administrator password. I initially tried to report this partially as a kde bug here with more information: https://bugs.kde.org/show_bug.cgi?id=345284 But it appears to affect other desktop environments as well and the main issue is that it never successfully resumes unless I reboot. It was originally on an older kubuntu but even after upgrading to 16.04 the issue persists. Relevant lsusb entry: Bus 001 Device 003: ID 1199:9041 Sierra Wireless, Inc.
