USB Hub doesn't work/only in charging mode

hello,

I bought this device:
http://www.amazon.com/Inateck-Ethern.../dp/B012N8KYWU
because it reads nice, I just got it but as i plug it in it only flashes and the tablet only detects is as chargeable device.
I can switch to RNDIS as i wanted to try ethernet, in the developer option but if I do that, the Pixel reboots and reset the option to the prior one.
It even doesn't recognize a USB Stick on that Hub.

Is the hub broken or is there another issue?

Thanks Avalun.
