USB 2.0 port2 is no working on custom carrier board

USB 2.0 port2 is no working on custom carrier board ,Could you please tell me how to fix the problem?

With almost 0 information here, I can only tell you to refer to the TX2 adaptation guide.

  • Is this USB system enabled by default? if need to enable it

What module is that? TX2? TX2i? TX2-4GB? TX2-NX?

What software release do you want to use?

At least tell such information when you file topic.
