    CX3  Device is not enumerated as USB3.0 device but USB2.0 device


      I develop a firmware. The firmware works perfectly on the CX3-based module. The module can be enumerated as USB3.0 device.But when I replace the CX3 board with my own board(I design and make according to the CX3 design schematics.And I recheck the design schematics, it should be ok.), the module can not be enumerated as USB3.0 device. The following figure is the USB trace.How can I fix the problem?
