And that's why I'm replacing the labels. If you open the bindings for usb-c-connector and for the snps,dwc3 host, you will see that both bindings describe HS/SS ports. DWC3 also describes a single port for usb-data-role switching, which can be used instead of HS/SS ports, but usb-c-connector doesn't have this option. -- With best wishes Dmitry
