The next gen universal connector standard have been shown in CES 2008 by USB 3.0 Promoter Group. The standard is backward capable with USB 2.0 and 1.0.

They did not show USB 3.0 in the work, but just show what it looks like. We have seem the normal connector and the socket in IDF few months earlier, but this time they show us a pic of the mini-socket.

the normal USB 3.0 connector

purple touch spots are for USB1.0 and 2.0 connection, the red ones are for USB3.

The definition.

The mini-socket, first shown to pubilc? It is clear the mini-socket isn’t backward capable.
