We want to know how to force the USB 3.0 port on the Jetson nano development board to work in USB 2.0 mode by software. We look forward to your reply. Thank you! In our design, a TOF camera is used, which is connected to the Jetson nano through a USB cable. Among them, TOF camera and USB cable support USB3.0 protocol type.

The problem now is that in the assembled vehicles, most USB TOF cameras are recognized as USB3.0 by Jetson nano and hung on the USB3.0 port, but the TOF cameras on several vehicles are sometimes recognized as USB3.0 and sometimes USB2.0, which is very unstable, resulting in the failure of TOF cameras on some vehicles.

Can you configure the Jetson nano so that some USB ports of Jetson nano work under USB2.0 protocol and others work under USB3.0 protocol? thank you!

I don’t know about doing so in software, but the easiest method would be to use a HUB which is only USB2. All devices which are USB3 would revert to USB2.

If USB3 fails, then it would most likely be from either power consumption being too high, or signal quality. A powered HUB would eliminate any possibility of failure from power delivery. Although it isn’t guaranteed, it is possible that a HUB would clean up the signal and fix the part of not always working as USB3 (if the HUB is USB3).
