STM32F4 Discovery - merge two USB descriptors

Dear all,

I'm using STM32F4 Discovery board and I wrote two separate projects:

  • Audio USB Device (that uses Audio class USB descriptor)
  • General purpose Device (that uses CDC USB descriptor)

How can I merge these two descriptors? I saw the UM0424 Application Note but the section related to the composite device is one page...

Thanks
