How to configure the Jetson Thor Type-C port to Host mode to read camera data?

Here is my attemp:
`ports {

		usb2-0 {
			status = "okay";
			mode = "host";
		};

		usb2-1 {
			status = "okay";
			mode = "host";
		};

		usb2-2 {
			status = "okay";
			mode = "host";
		};

		usb2-3 {
			status = "okay";
			mode = "host";
		};

		usb3-0 {
			status = "okay";
			nvidia,usb2-companion = <0x01>;
		};

		usb3-1 {
			status = "okay";
			nvidia,usb2-companion = <0x00>;
		};

		usb3-2 {
			status = "okay";
			nvidia,usb2-companion = <0x03>;
		};

		usb3-3 {
			status = "disabled";
		};
	};

	prod-settings {
		#prod-cells = <0x04>;

		prod {
			prod = <0x00 0x88 0x21fe0000 0x1ba0000 0x00 0x94 0x3c00000 0x1000000 0x00 0xc8 0x21fe0000 0x1ba0000 0x00 0xd4 0x3c00000 0x1000000 0x00 0x108 0x21fe0000 0x1ba0000 0x00 0x114 0x3c00000 0x1000000 0x00 0x148 0x21fe0000 0x1ba0000 0x00 0x154 0x3c00000 0x1000000 0x00 0x288 0x3fff000 0x51e000>;

	};
};

};`

With these changes, the Type-C port is now successfully powering the hub and it can work. However, we are still only able to read data from one camera at a time. We have confirmed that all our cameras are working correctly.

Could you please advise on how we should further modify the device tree to resolve this? Looking forward to your reply.

Hi,
Please refer to the suggestion in
Using 3 USB 2.0 cameras with a Jetson Thor - #3 by DaneLLL

and see if you correctly modify the device tree. And please check if you use USB3 cameras and the cameras are enumerated as SuperSpeed.

Also you may connect some cameras to the type-A ports on developer kit, to use bandwidth of another roothub.
