Hello everyone,

   

Why SS_RX_P is connected to STDB_SSRX-, respectively SS_RX_M is connected to STDB_SSRX+, and not the reverse ?

   

Is that a mistake?

   

Thanks in advance.

   

Regards

Hi Stephane

   

It is not a mistake. USB spec allows this flexibility to interchange the polarity on SS_RX_P/SS_RX_N. The polarity inversion will be taken care during the device enumeration, so the board design can be done after looking at the layout considerations.
