"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,
Radka
