USB 2.0 port is not working on our Carrier Board

We new our Carried board with TX2, Connect USB1_D+(A38) and USB1_D-(A39) to USB2.0 port.
But the usb is not working.
Type command ‘lsusb’, nothing message to show in the terminal.
if install TX2 on Nvidia Carrier board, I can see Linux Foundation 3.0 root hub and 2.0 root hub.
Can you provide us any guide on how to fix the issues?

Also, If install TX1 module on our carried board , the usb is working correctly.

Are there any difference between TX2 and TX1 on USB?
