A Brand New usb 3.0 Hub not recongized

I have a New 15inch Retina MacBook Pro.  The USB3.0 ports recongize all 2.0 devices.... and a USB 3.0 Passport.... But Not a USB 3.0 HUb nor  brand new 3.0 to Gigabit ethernet.   All updates are current.

I spent a couple of days trying to figure out who the manufacturer was. The hub itself has no identification on it to indicate the manufacturer; came without any documentation; no box; no manufacturer info from the seller. The seller has thus far been helpful and says that I am the first person to have had a problem with it.
I just tracked down what may be the manufacturer. Here's the page with the port: http://vina.manufacturer.globalsources.com/si/6008822920529/pdtl/USB-hub/1003936 496/USB-2.0-Hub.htm
I may contact them but my Chinese is not very good.
On the other hand, it was very cheap. Less than 6 bucks, including shipping. I may use it as a paperweight.
