6.1.2.1 Common USB Routing Guidelines
If routing to USB device or USB connector includes a flex or 2nd PCB, the total routing
including all PCBs/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/areas or power supply components
