I am using FX3 Development kit, and found that, the SS_RX_P and SS_RX_M signals are reversed on the USB3.0 Micro type-B socket in the shcematic. Is there any body knows why?

USB3.0 allows checking the polarity through hardware handshake and reverse the polarity if needed (Make the life of PCB designers easy by making the routing of the USB3.0 lines easier). That is the reason behind the swap.
