对应的dts已经配置成usb3 enable，但是通过反编译出来的dts usb3.0 确实disable，请帮忙确认一下那地方配置不太对感谢。

Hi,

因為這個dtsi file你這個dts不會用到… 麻煩自己track一下code

28

嗯嗯好的，我自己看先一下，感谢

已经把usb3-2 enable起来，但是usb3.0还是识别到

帮忙看一下usb3-2还有什么地方没有配置正确，感谢

還是先讀個文件吧 看起來跟你的硬體完全沒有對上

这个文档我看了看了好多次了。 我们自定义的板子是USBSS2 对应的软件是usb3-2吗

32

是的

33

nvidia,usb2-companion` : USB2 port (0, 1, or 2) to which the port is mapped.
这个usb2 port对应硬件是哪个地方

 ports {
        ...
        usb2-1 {
              mode = "host";
              status = "okay";
            };
            ...
            usb3-2 {
                  nvidia,usb2-companion = <1>;     //????
                  status = "okay";
            };
            ...
 };
};

你的schematic上面usb2的部份是用哪一根pin就要寫多少.
