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_hid_generic_desc_t
	Interface descriptor structure for HID generic. More...
struct	udi_hid_generic_report_desc_t
	Report descriptor for HID generic. More...

Macros
#define	UDI_HID_GENERIC_DESC
	By default no string associated to this interface. More...

#define UDI_HID_GENERIC_DESC

By default no string associated to this interface.
