I believe that this option fails to actually re-enable USB until complete reboot of a machine affected. Neither keyboard, nor mouse, nothing, no USBs work after switching from power (dock) to battery, even after re-connecting power.
The issue is observed since upgrading to F28 (non-gnome)
Is there anything I can look at to find out what is causing it, if it is really due to the above mentioned power saving tweaks?
F28 only enables auto-suspend on BlueTooth USB interfaces, all other USB devices are
left alone, so this seems unrelated.
Not exactly since it's happening only since the update and I don't know what else it could be...
Further I do use a bluetooth keyboard that I am unable to connect anymore (so i use it through synergy from windows machine...)
Regards,
Hans
