I’m creating a custom carrier for Jetson orin nx which uses USB3-2 with usb2-2 companion following this schematic i have updated the dtb to match these changes

when i connect a camera to USB3-2 it detects the video device and speed as usb3 but the stream is corrupted can’t get frames from the camera, uvc video shows error code -71 although it works on the devkit on USB3-0, so is there something missing in DTB configuration that makes it different? (camera is externally powered)
