Any of USB3 ports not working on Mac Mini Late 2012

I wonder why no USB3 device is recognized by my Mac Mini late 2012 with MacOS 10.13.3, all ports work only as USB2.

 

I bought a new USB3 pen drive and it does not even appear connected ???

 

What should I do?

Is this one of those amazingly cheap flash drives out of China?*

 

Because if they are amazingly cheap, it is because they are amazingly fake. It is a known scam. It may mount somewhere and even look like its supposed capacity but trying to copy more than a minimal amount of data onto it will fail because they use reject undersize chips and alter the way it reports its capacity to your OS.
