Hi,
Sorry I thought you have two sets of USB3 pins in the design. And there’s only usb3-1. So it should be valid. Please refer to

And if extcon state is well configured, please check tuning guide of compliance test to adjust the signals. The error print can be because power supply is not stable or signals are not good.
