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_multi_touch_desc_t
	Interface descriptor structure for HID multi-touch. More...
struct	udi_hid_multi_touch_report_desc_t
	Report descriptor for HID multi-touch. More...

Macros
#define	UDI_HID_MULTI_TOUCH_DESC
	Content of HID multi-touch interface descriptor for all speed. More...
#define	UDI_HID_MULTI_TOUCH_STRING_ID   0
	By default no string associated to this interface. More...
