    CYUSB3014 unable to  be detected by PC



      I used CYUSB3014 in my design and referenced the design of a third-party development board. After connecting to the PC with a cable, the device manager of the PC cannot find the device, and the measured voltage and crystal clock output are normal, but compared with the development board, it is found that when the PC is not connected, the DP pin of the development board is high ( 3.3V), and the discipline on my board is about 0.6V. What could be the cause of this problem?


      Attachment here is the schematic (the clock uses X2, Y2 is not soldered).
