[Arm-netbook] USB3.1 pinout

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) but on elinux.org there are four differential pairs for only one USB interface. Are the other two pairs meant to be used by the second USB port or did I miss something?

Thank you very much! Julius Lehmann
