Make and model of the drives and/or enclosures you've tested?

Is it only things that use that enclosure?  Do other USB devices work properly using that port.. thumb drives, external monitors, etc.

Only other device with USB C is hub, and it working. 

So it would mean that the case is faulty, but the question is why?? It works on other computer, so why not here??

It's sadly common to see 3rd party USB-C devices work with some comptuers, but not others. In my opinion, manufacturers test them with two or three brands and send them out the door. 

 

I'd try a different brand of enclosure. One that states Lenovo compatibility, if you can find one. Or a USB-3 enclosure.
