void usb_user_endpoint_init

(

uint8_t

conf_nb

)

This function configures the endpoints of the device application.

This function is called when the set configuration request has been received.

The core of this function should be correctly rewritten depending on the USB device application characteristics (the USB device application has specific endpoint configuration).

This function is called when the set configuration request has been received.

bool usb_user_get_descriptor	(	uint8_t	,
		uint8_t

This function returns the size and the pointer on a user information structure.

bool usb_user_read_request	(	uint8_t	type,
		uint8_t	request
	)

This function is called by the standard USB read request function when the USB request is not supported.

This function returns true when the request is processed. This function returns false if the request is not supported. In this case, a STALL handshake will be automatically sent by the standard USB read request function.
