USB interface descriptors

The following structures provide predefined USB interface descriptors.

It must be used to define the final USB descriptors.

Data Structures
struct	udi_vendor_desc_t
	Interface descriptor structure for vendor Class interface. More...

Macros
#define	UDI_VENDOR_DESC
	Content of vendor interface descriptor for all speeds. More...
#define	UDI_VENDOR_DESC_FS
	Content of vendor interface descriptor for full speed only. More...
#define	UDI_VENDOR_DESC_HS
	Content of vendor interface descriptor for high speed only. More...
#define	UDI_VENDOR_EP_NB   (UDI_VENDOR_EP_NB_INT+UDI_VENDOR_EP_NB_BULK+UDI_VENDOR_EP_NB_ISO)
#define	UDI_VENDOR_EP_NB_BULK   ((UDI_VENDOR_EPS_SIZE_BULK_FS)?2:0)
#define	UDI_VENDOR_EP_NB_INT   ((UDI_VENDOR_EPS_SIZE_INT_FS)?2:0)
	By default no string associated to this interface. More...
