How to make USB3.0 operate as a device or dual role?

[kim760407]

Hi.
I would like to connect the USB3.0 peripheral of the SOM to my PC and have my PC recognize the SOM as a device. I set the usb controller to device mode (UFP), updated the device-tree to set USB3.0 node from "host" to "peripheral", and if I connect a webcam to this port, the webcam is not recognized. So it seems to be in device mode. If I connect the USB3.0 port to my PC, my PC does not recognize the SOM as a device though. How can I see the SOM as a device on USB 3.0?
Thanks for your help,
Kim
