It's probably failing Rx.Detect and falling back to high-speed.

I recently found that if I plug the device into itself (there are two dwc3, one on a C port, one on a female A port) the device enumerates at superspeed with the NCM configfs driver. But connecting to my x86 machines fails. In an earlier thread I found that the type C port would not work with USB2 or 3 if in the "normal" direction (as opposed to "reversed"). ^ permalink raw reply [flat|nested] 6+ messages in thread

Can you capture dwc3 tracepoints?
