There are three sets of differential pairs associated with each SuperSpeed USB port. One set for High-Speed and two sets for SuperSpeed.
WARNING
Do not connect the USB2 and SS USB connections on one USB3 connector to two different host chips. For instance, do not use the SS USB TX/RX from the TUSB73x0 and the USB2 DP/DM from another USB2 host.
Doing this may cause USB compliance failures and xHCI driver issues.
