How can I change USB2. 0 port 0 to host mode, on AGX Xavier

JETSON AGX Xavier USB2.0 port 0 default work on device mode. How can I set this port work on host mode? We have USB_5V supply for USB port. But this USB port not support OTG mode.

Hi,
The micro B port is for uart log and works in device mode only. We are not able to set it to host mode. The OTG port is J512(type-C) port. This is the design of Xavier developer kit.

How about USB2.0 port1~3? These ports only work on host mode, or host mode and device mode both?

Hi,

Only one port can be used as OTG port. You may refer to product design guide for designing USB lane mapping and adaptation guide for software device tree programming.
