Hey there!
I was wondering about the USB3.1 pinout in the EOMA68 standard. In my research on the USB Type C connector I found out that USB3.1 (Superspeed+) has only two differential signal pairs (one for receiving, one for transmitting)

two for receiving, two for transmitting, each 5gbit/s for a total of 10gb/sec. the connector and thus the pinouts are rotatable by 180 degrees so the pinouts on the first 12 pins (top row) are *identical* layout to the second 12 pins (bottom row) except in the reverse order. D+ and D- (the USB2 pins) are *missing* on one row of the receptacle so that you don't connect them up twice (which would be bad).
you *may* be thinking of USB 3.0 which is connector-compatible with USB 2.0 and is what you find on most laptops and desktop computers these days:

that is *only* one set of (5gbit/sec) tx-rx differential pairs.
scared me for a minute that i'd messed it up... :)
