Old thing i think. Already discussed long ago,

I even made an article about it(in my language), i already read all of the whitepaper, since i also need to work with that protocol of SUPER SPEED USB.
And yes, i fail. The speed that too fast is only worth for video and such.
I don't really like a connection with separated TX - RX. It's like back to the old days. But well, it is needed, since more power and more speed is needed. But it is really weird that the D+ and D- will be just an accessory there.
When it comes out, just some of PC that high end can handle it. I don't want to spend money more for them. I can say that i will wait patiently. That's from me.
