USB3 disks not recognized in USB3 ports (16.04.2 LTS)

I have had problems with USB3 ports for some time. Now, after a recent update, when I connect external USB3 disks to any of my USB3 ports they are not recognized.

USB2 devices (for example) do work when connected to these USB3 ports (and USB3 disks are powered when connected to USB3 ports, but not recognized).

My USB3 disks do work when connnected to USB2 ports.

When I run other operating systems, these ports do work.

What can I do to make USB3 devices work with my USB3 ports again?
