USB slots stop working suddenly from time to time
The usb ports of my laptop fail for some reason from time to time. This concerns apparently mainly the external mouse and keyboard connected by usb, while connecting an external hard disk to the same ports may activate them. All gets back to normal after restart. How could I get the same effect without restart?
Since the issue reemerges after reinstalling OS and due to random variations I have created a new question asking for a permanent solution.. In case I get an answer I will close this one.
EDIT: /sys/module/usbcore/parameters/autosuspend
contais only the line 2
.
/sys/bus/usb/devices/usb2/power/autosuspend
and /sys/bus/usb/devices/usb3/power/autosuspend
contain 0
(This was verified after solving the problem by restart, not before..)
I do not see Legacy USB Support in BIOS
I have edited and updated this question because I have some answers and comments here: but for new solutions please try answering my new question.
sudo -s
and pasted the main for loop of that script. Spits out some file-not-found errors, but still works.
