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_kbd_desc_t
	Interface descriptor structure for HID keyboard. More...
struct	udi_hid_kbd_report_desc_t
	Report descriptor for HID keyboard. More...

Macros
#define	UDI_HID_KBD_DESC
	Content of HID keyboard interface descriptor for all speed. More...
#define	UDI_HID_KBD_EP_SIZE   8
	By default no string associated to this interface. More...

#define UDI_HID_KBD_DESC
