on my board we designed, we use usb2.0.1 and usb 2.0.2 for host and usb type A port, we change device tree. but still have problems.
the log as follow:

I have changed the device tree according to the adaptation. Because there is no usb device so I remove the USB PD controler part and xudc part.

I plug the usb mouse into the usb type A port, the led on mouse don’t flash. and no any information in kernel. no any information when use the command “lsusb”.
