您好，想请教一下：
我们自研的主板，原理上USB部分跟套件基本一致，之前使用Jetpack5.1.3 USB功能是正常的，现在更换到Jetpack6.2后USB功能不能使用了（我们主板上是从HUB上出来的一个USB2.0和USB3.0）
未修改dtb内usb部分，进系统后查看usb相关信息

The Jetson AGX Orin platform has various USB-related features and components. Here’s a comprehensive overview:
USB PHY: The Jetson Orin module has a USB PHY (Physical Layer) component, which is responsible for managing the USB interface. The USB PHY is connected to the Orin module’s USB ports and provides the necessary signals for USB communication.
USB Ports: The Jetson AGX Orin platform has multiple USB ports, including USB 3.2 and USB 2.0 ports. The USB ports are connected to the Orin module’s USB PHY and provide connectivity for various USB devices.
USB Pin Description: The Jetson Orin Module USB 3.2 and PCIe Pin Description table provides detailed information about the USB pins on the Orin module. The table lists the pin numbers, signal names, and descriptions for the USB 3.2 and PCIe interfaces.
USB 3.0: The Jetson AGX Orin platform supports USB 3.0, which provides faster data transfer rates compared to USB 2.0.
USB CAN interface: The Jetson AGX Orin platform has a USB CAN (Controller Area Network) interface, which allows for communication with CAN devices.
USB RCM Mode: The Orin module can be put in USB RCM (Recovery Mode) mode, which allows for flashing and recovery of the module.
Comparison with Jetson Xavier NX: The Jetson Xavier NX series also has USB-related features, including USB 3.0 support and a USB CAN interface. However, the Jetson AGX Orin platform has more advanced USB features, including USB 3.2 support and a more comprehensive USB pin description.
In summary, the Jetson AGX Orin platform has a robust USB subsystem with multiple USB ports, USB PHY, and support for USB 3.2 and USB CAN interfaces. The platform also has a comprehensive USB pin description and supports USB RCM mode. While the Jetson Xavier NX series also has USB-related features, the Jetson AGX Orin platform has more advanced USB capabilities.

A very common topic. Please refer to below post first.
您好，可能是我没太理解官方文档如何去修改device tree，因为我们现在USB原理设计部分跟官方套件一致，我们认为不修改dtb中usb部分也是可以的；如果您认为是要修改的，能否提供下具体要修改的地方
因为我们现在USB原理设计部分跟官方套件一致
這句話我已經聽了很多用戶這樣講過. 但澄清到最後結果都是跟NV devkit沒有一樣.
麻煩理解一下. 沒有所謂"基本一致"這種事情. 只要有任何一個東西不一樣, device tree就不能直接用.
比方說好了, 你貼了一個usb2-3, 一個UPHY0_TX/RX2. 那其他NV devkit上存在的東西你的板子上有嗎?
