A603 carrier board: One USB type A ports locked at USB 2.0 speed

There are two USB type A ports on the A603, and the spec says “2xUSB3.0 Type A (Integrated USB2.0)”. But I’m finding that one of the ports seems to be restricted to USB 2.0 speeds. When I use lsusb with my camera plugged into port 1, I get this:

/:  Bus 02.Port 1: Dev 1, Class=root_hub, Driver=tegra-xusb/4p, 10000M
    |__ Port 1: Dev 3, If 0, Class=Miscellaneous Device, Driver=, 5000M
    |__ Port 1: Dev 3, If 1, Class=Miscellaneous Device, Driver=, 5000M
    |__ Port 1: Dev 3, If 2, Class=Miscellaneous Device, Driver=, 5000M
/:  Bus 01.Port 1: Dev 1, Class=root_hub, Driver=tegra-xusb/4p, 480M
    |__ Port 3: Dev 3, If 0, Class=Hub, Driver=hub/4p, 480M

But when I connect it to port 1, I see this instead:

/:  Bus 02.Port 1: Dev 1, Class=root_hub, Driver=tegra-xusb/4p, 10000M
/:  Bus 01.Port 1: Dev 1, Class=root_hub, Driver=tegra-xusb/4p, 480M
    |__ Port 3: Dev 3, If 0, Class=Hub, Driver=hub/4p, 480M
        |__ Port 1: Dev 9, If 0, Class=Miscellaneous Device, Driver=, 480M
        |__ Port 1: Dev 9, If 1, Class=Miscellaneous Device, Driver=, 480M
        |__ Port 1: Dev 9, If 2, Class=Miscellaneous Device, Driver=, 480M

Since they’re supposed to both work at high speed, can anyone tell me why one of them won’t? I haven’t done anything to restrict the speed. Is there some way I can unlock this? What does it mean when it says “integrated USB2.0”?

Thanks.

Hi @theosib
I found the same problem with my A603. Did you get any new information about it? Or found workaround to unlock the second port?

Hi there,
It’s the ZIF socket that’s the integrated USB3 & USB 2.0
Be sure you have the correct wiring for the port.

Hello, what version of JP are you using. We’ll check it for detail.
BTW, would you please sending me the dmesg log?

dmesg > dmesg_603.log

Hi Seraphna,
here the dmesgs you requested.

First try: Camera inserted in the bottom USB3

Tested with a Orin NX + A603 where I flashed Jetpack 5.1.2 and the drivers you provided.
