How to disable auto power off of usb devices like usb mouse?


I don't know how , but somehow automatic power-off of usb devices got accidentally enabled. Now my usb mouse goes off even if it's idle for 2-3 seconds. It's really irritating.


This happened after I installed powertop and powernap. Maybe it has something to do with these two applications.


How can I disable this "feature"?



It's PowerNap that's doing this.


You can disable just this part of PowerNap's power savings scripts with:


sudo powernap-action --disable usb_autosuspend
