7.1.2.1 Common USB Routing Guidelines
If routing to USB device or USB connector includes a flex or 2nd PCB, the total routing
including all PCBs and flexes must be used for the max trace and skew calculations.
Keep critical USB related traces away from other signal traces or unrelated power traces and
areas or power supply components.
