Detailed Description

This file contains the functions to recognize an elomax unit when it is connected and disconnected from the usb-bus.

The elomax_driver_probe() and elomax_driver_disconnect() functions in this file are via the 'driver table' (see elomaxdriver.h) communicated to the usb-core. The usb-core calls these functions when an elomax driver is connected and disconnected from the usb-core.

Function Documentation

static void elomax_driver_disconnect

(

struct usb_interface *

interface

)

[static]

This function destroys the instance for the just disconnected elomax unit.

This function is called by the usb-core when an elomax unit is disconnected from the usb-bus. It uses the supplied struct usb_interface to refind the attached instance (via usb_get_intfdata()), destroys this instance by calling elomax_instance_destruct() and resets the pointer from the interface to NULL (via usb_set_intfdata()).

Parameters:

[in]

interface

The interface which is disconnected from the usb-bus.

static int elomax_driver_probe	(	struct usb_interface *	interface,
		const struct usb_device_id *	id
	)			[static]

This function creates an instance for the just connected elomax unit.

This function is called by the usb-core when an elomax unit is connected to the usb-bus. It checks if the connected unit is really an elomax unit, then calls elomax_instance_construct() to create an instance for this unit. This instance is then attached to the struct usb_interface via usb_set_intfdata().

Parameters:

[in]	interface	The data-structure in which the usb-core keeps its administration for this unit.
[in]	id	Additional information the usb-core supplies about the probed device.

Returns:

The successfullness of the creation of the instance.
