    Can USB2.0 pair (D+, D-) of CYUSB3014 swappable?

    jintao.zheng

       When we layout the PCB of our first USB3.0 product, we found that the D+ (A9) and D- (A10) have to be crossed each other when rounting to the type B USB receptable connector (Pin3 is D+, Pin2 is D-), we're using Type-B through hole receptable and USB3.0 chip (3014) on the same side, In Appilcation Notes 70707, there's part of the pcb layout which doesn't show such cross...we're wondering if we made mistakes on the pin layout of the USB chip or the USB connector...but we checked several times....AN70707 mentioned the USB3.0 pairs can be swapped ...but not mention the USB2.0 pair ...any clue? Thanks!
