USB3.2 speed On jetson Orin NX

Robotics & Edge Computing Jetson & Embedded Systems Jetson Orin NX

Hello everyone. I’m using a setup consisting of a Jetson Orin NX and another device from Luxonis. The device is USB3.2 capable (10gb/s) . I’m using the official Jetson Orin Nano carrier board, and the device is connected to one of the USB ports.
I’m using Jetpack 5.1.2
The problem is that the bandwidth i’m getting is 5gb/s (USB3.1) despite the fact that is is clearly stated that Jetson Nano can go up to 3.2 .
Can anyone help ?

Just to clarify

  1. Your product is a Jetson Orin NX.

  2. Orin NX is not same as Orin Nano. Orin Nano is not Jetson nano. Jetson nano is a product that released 5 years ago with old SoC.

  3. What is the result if you connect that USB device to the type C port? Adapter might be needed.

Indeed Orin Nano is not the same as NX , my bad. But i’m using the carrier boad of an Orin Nano devkit for my prototyping. I cannot plug the device on the usb-c port since i don’t have a Usb-c 3.2 compliant cable with me right now. I will do the test as soon as i have my cable.
But i tested my device on a custom carrier board , that does not have a usb controller and the result was the same. I’m saying that just in case your concern was about the usb controller.

Could you share the lsusb -t result after you connect the device?

I connected the device to the usb-c port on the carrier board as you asked yesterday. The cable is 3.2 capable for sure.
Here is the output of lsusb -t :

    |__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/4p, 10000M
    |__ Port 2: Dev 3, If 0, Class=Vendor Specific Class, Driver=usbfs, 10000M
/:  Bus 01.Port 1: Dev 1, Class=root_hub, Driver=tegra-xusb/4p, 480M
    |__ Port 2: Dev 2, If 0, Class=Hub, Driver=hub/4p, 480M
    |__ Port 3: Dev 3, If 0, Class=Wireless, Driver=rtk_btusb, 12M
    |__ Port 3: Dev 3, If 1, Class=Wireless, Driver=rtk_btusb, 12M

Additionnally i did a dmesg --follow to capture kernel driver messages when i plug the device :

@WayneWWW Hello. Any update on the subject ?

8

So current situation is the type C port can work fine with USB3.2 speed but the usb hub cannot?

Do you have the log for that hub situation?

9

@WayneWWW No no in both cases the bandwidth is stuck at 5gb/s (USB3.1) , the logs before show USB3.2 .

10

So what is this log doing here?

11

Showing that my problem has noting to do with the hub actually…

There is no update from you for a period, assuming this is not an issue anymore.
Hence, we are closing this topic. If need further support, please open a new one.
Thanks

Sorry, I don’t get what you are trying to tell here.

  1. You gave us a usb3.2 log and you said it is on the type C port. This result/log indicates usb3.2 works on type C port of Orin NX.

  2. I asked you so this issue would only reproduce on the usb hub on Jetson?

  3. Now you told me (2) is wrong and also (1) is wrong too.

So where did you get the log in (1)? What is the point to post that log?
