Would anyone know what might be causing "unknown" and non present devices? The devices continually reinstall themselves, even after being uninstalled?
Below is a small snapshot of the Device Manager.
I only have a keyboard, mouse and external drive in use.
nothing more is connected via USB.
Yet those three unknown devices keep showing up?
Any questions or suggestions, about this would be great.

Double click on them, click on the Details tab then in the Property drop down, select Hardware IDs. Click on the top one then press Ctrl+C to copy it to the clipboard then paste in a reply here. Do all 3.
Install latest version of Chipset driver to it will resolve the problem.
Downloads for Intel(R) Z170 Chipset
What I don't see in Device Manager's USB section is mention of Enhanced in one or more items which designates USB 2 support. Could be the drivers are not installed for USB 2 [usually come with the motherboard] or those ports are dead.
Mine [yeah, it's busy]:
All the ports are working.
Not sure about the chipset.
If I plug something in to every port.
They all work fine.
Why are you not sure about Chipset driver installing it wont cause any problems.
Chipset driver will include USB controller driver.
