USB3 drives not discovered when plugged into USB3 port
Hello,
Lately, any USB3 drive is not discovered when plugged into the USB3 port.
USB2 mode works.
It worked, say, till two months ago, have no idea about what went wrong.
Could you help me debug this problem, please?

Re: USB3 drives not discovered when plugged into USB3 port
reloading the xhci module did the job
sudo modprobe -r xhci_hcd
sudo modprobe xhci_hcd
how to solve this issue without this user intervention?

You could try putting the module name in a file in /etc/modules-load.d/ -- I have no idea if that would work, but the name of the directory suggests it would be worth a try

tried, NOT working, tnx anyway 
the xhci_hcd module is always loaded at boot, I need to unload and reload it AFTER plugging the USB3 drive..
