USB 3.2 port on a custom carrier board limited to gen1 speeds

[xlucny]

Hi,

According to Orin nano datasheet, all USB 3.2 ports are capable of running at 10Gbit speeds. I tried testing this on my custom carrier board with a USB 3.2 Gen2 device (a USB stick), but it seems that it is limited to gen1 speed. It’s not achieving the write/read speeds it is supposed to and in lsusb I can see that 10Gbit is not listed as a supported speed.

  wSpeedsSupported   0x000c
      Device can operate at High Speed (480Mbps)
      Device can operate at SuperSpeed (5Gbps)

Now for the sake of argument, let’s assume that the device - usb stick - is ok. Do you know of any other issues that might prevent the USB (A) port from achieving 10Gbit speeds?

Jetson Orin nano, Jetpack 6.0

What is the speed of this USB stick when it is put on devkit?

I tested it on an AGX Orin devkit and, although lsusb reported still the same, the speeds were okay - about 800 MB/sec when connected to the USB A ports next to the displayport. I then however tested it again on the original carrier board and the speeds were also okay.

@WayneWWW I’m really sorry for this. It seems that everything was okay the whole time. I must have somehow messed up what speeds was it supposed to achieve.
