你好我有一塊客製化的Orin NX，我在USBSS2上接一個usb hub，該hub與USBSS0所接的hub一樣(與公版使用的一致)。
我將ID_I2C_SCL與ID_I2C_SDA接在USBSS2的usb hub上，做usb hub初始化。
請問ID_I2C_SCL與ID_I2C_SDA需要做設定嗎?
下圖為USBSS0連接的usb hub。
ID_I2C_SCL與ID_I2C_SDA接的位置跟CAM_I2C_SCL與CAM_I2C_SDA一樣。

The provided text does not contain the necessary information to answer the question. The question seems to be asking about the USB hub and I2C connections on the Jetson Orin NX module, but the text does not provide a clear explanation of these connections.
However, based on the provided text, here is some general information about the USB and I2C connections on the Jetson Orin NX module:
- The Jetson Orin NX module has multiple USB 2.0 and USB 3.2 interfaces.
- The USB 3.2 hub design uses a Realtek RTS5420 device.
- The hub circuit includes a SPI FLASH device that holds configuration information.
- The Jetson Orin NX module has multiple I2C interfaces, including I2C 1x-1.8V and I2C 3x-3.3V.
It’s also worth noting that the question mentions specific pin names and IDs, such as USBSS2, I2CSCL, and I2CSDA, but the text does not provide a clear explanation of these pins and their connections.
To provide a more accurate answer, more information is needed about the specific question being asked and the context in which it is being asked.

Hi,
Only make sure the pinmux is correct and i2c controller is enabled.
pinmux有設定
/opt/nvidia/jetson-io/jetson-io.py
確認40pin ID_I2C_SCL與ID_I2C_SDA是27、28
從/dev/i2c*確認有/dev/i2c-2
請問這樣是i2c控制器有啟用嗎?
device tree 有USBSS0的設定

對USBSS2也要設定一個嗎?該怎麼設定?
please refer to document.
USBSS2連接hub，ID_I2C_SCL與ID_I2C_SDA有必要接嗎?
在device tree中有將usb3-2啟動。
Please check with the hub vendor if that is needed.
我沒有看到對於Type A、I2C的設定，另外hub ic 與公版是同一個，應該如何設定?
Type A is the simplest case. If your hardware is correct, then following the same device tree setting as NV devkit but switch to your data lane setting would work.
vbus-supply may also need to meet your design.
請問我應該從device tree的哪裡做修改?
