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).

bool usb_user_read_request	(	U8	type,
		U8	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.
