> "Enable USB autosuspend for USB bluetooth receivers by default. If all other USB devices on the laptop also have USB auto-suspend enabled (which typically is true) this saves aprox. 0.4 Watts of power on an idle laptop."
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?
Thank you,
