    I have a question about device descriptor settings


      I am trying to create a combined device of dual CDC and mass storage class in USBUART component of Psoc5lp.

      I am using the USBUART_SerialNumString function to set the USB serial number but I can not set it.

      Is there anything wrong with the device descriptor settings?



      The device descriptor registers the following three things for reference, and it is possible to set the USB serial number for 1 and 2 using the USB UART_SerialNumString function.


      1. Dual CDC 2. Single CDC 3. Dual CDC and MSC
