USBSS2 cannot find usb3.0 device on Orin NX

USBSS2 connects to the hub, but no usb3.0 device can be found on the hub. In the retest of Jetson_Orin_NX Demo board, no USB 3.0 can be found on USBSS2 (a port below J6), please help to check. USBSS1 can be found. USBSS2 oscilloscope did not test the USB3.0 grip signal

USBSS2 接hub,hub上找不到USB 3.0设备,在Jetson_Orin_NX Demo 板复测,USBSS2(J6的下面一个端口)找不到usb3.0, 请帮忙看一下,USBSS1是可以找到,USBSS2 使用示波器没有测试到USB3.0的握信号

Do you mean your usb device can not be detected on under port of J6? Both ports of J6 are routed to same USB hub chip on devkit carrier, and so the port of J7. Could you test more usb devices on these all ports and also can test more Orin NX module if possible.

Orin NX devkit usb3.0 cannot be recognized,only obtain usb2.0.

如上图,u盘 只能识别到usb2.0,没办法识别到usb3.0,需要怎么配置,帮忙告知一下,感谢

Can you share the schematic? All four ports should be from same USB hub. USB2 and combined USB3 of each port should route together.

Can you share full USB part design including all USB2.0 and USB3.0 lines?

The picture above is our company’s custom board

This problem is urgent, please help to reply,Thanks

Where is the “USB1_N/P_HUB” coming from on your schematic?

please attach full dmesg.

dmesg.txt (66.7 KB)


By default this device tree does not enable usb3-2 at all. Did you ever read the document and modify the device tree?

换了一个usb3.0 U盘,但是还是识别成usb2.0,具体log如下:

厄… 請問一下是不是沒有看懂我上面的回覆…



就software來說是這樣沒錯, 但我這邊沒有完整review你的硬體部份有沒有問題.
