Yes, exactly. I faced with similar devices a few years ago. But I ordered it on Ali Express. Unfortunately these devices does not support Windows Vista or higher and GNU/Linux. One of devices does not work at all...
And Ebay is not good variant for my country. I live in Belarus and a lot of traders does not send goods in my country or makes very expensive shipping (more that 35 USD).
I need device that supports Windows 10, And it would be cool if Ubuntu 14.04 is supported also.
