    The host cannot detect a board using CY7C65215

    EiLe_3184711

      Hello,

       

      I designed a board using the chip CY7C65215 based on the schematic shown in the datasheet. I didn't use the MCU, the Battery Charger and other peripherals as the datasheet said.  When I connected the board to my PC via a USB cable, the PC cannot detect a new USB device, neighter the USB Serial Configuration Utility.

       

      The schematic diagram is as below. Does it meet the minimum requirements for the chip to work? I had check the schematic and the PCB for a whole day, but I couldn't get any solution. Who can tell me if I miss somthing?

       

      Thank you very much!
