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_gpd_desc_t
struct	udi_hid_gpd_report_desc_t

Macros
#define	UDI_HID_GPD_DESC
#define	UDI_HID_GPD_EP_SIZE   8
#define	UDI_HID_GPD_STRING_ID   0

#define UDI_HID_GPD_DESC
