Can the differential pair polarity be swapped on the ST ECMF04-4HSWM10, e.g. USB_SSTX_P connects to D1-, USB_SSTX_N connects to D1+?

Yes, they can be swapped. Be sure that pin 1, 2, 4 and 5 are connected to connector, as there is ESD protections on this side.

Thank you for confirming that, Fabrice.
