USB Bus 1 defaults to USB 2.0. I need 3.0 support for a camera. How can I modify the configuration to be USB 3.0.

If you are implying changing the dev carrier board USB connectors to USB3 on both of them I don’t think you can do this.

The micro-OTG connector does not have the actual wires required for USB3.

I do not believe there is a second USB3 controller (hardware) which could be routed to a second connector. A second connector at USB3 would require a HUB (and the bandwidth provided in total among HUB ports would equal a single USB3 port max).

If you need true USB3 speed on multiple USB ports you will probably need to install a PCIe adapter. Else you can achieve what you are looking for with a USB3 external HUB on the full-sized connector.

Thanks for the response, it caused to me to dig deeper. The issue is not with the TX2. It supports USB 3.0 on the Type A connector as expected. The problem is in software. Thanks.

It is not possible because it only connects to USB2.0 in HW. Please refer to HW design of default carrier board:
