Is there any documentation on the various USB descripor formats supported by the FX3?  In particular all of the formats that are part of the enum CyU3PUsbDescType.   These get passed to CyU3PUsbSetDesc() as an array of uint8_t so understanding a little more about what is being passed would help me a bit.  Or, is the 'documentation' just the sample code- i.e. I can copy and modify existing structures from the examples?

The format for the USB Descriptors are available in USB Specification. This is generic to all the USB devices, not just FX3.
