Unfortunately this does not explain why you get an invalid port status port speed from the downstream ports of the LAN hub. The following diagram depicts dwc3 integration in AMx. Those are the two instances available on AMx devices, Dynamically changing the mode of operation can be useful for debug purposes but this should never be used in production.

But I am doing pretty much the same thing. Those are the two instances available on AMx devices, But there is one difference between your and my implementation.

It kinux not documented but there seems to be a bit of info aroud the net since a lots of Soc manufacturers use it. I'll keep plugging away.

Please note as of Wednesday, August 15th, this wiki has been set to read only. In order to use it, you must first mount that file system in case it's not mounted yet.

We did videoconferencing but using already compressed video from H cams. You will need a mini-A to Type-A adapter to use the Host port. And a modified version of the EHCI driver: I have tried different hubs, input devices AND different boards all based on the RK — the problems still persist.
