DEVICE_INTERFACE_CHANGE_NOTIFICATION structure (wdm.h)

The DEVICE_INTERFACE_CHANGE_NOTIFICATION structure describes a device interface that has been enabled (arrived) or disabled (removed). The PnP manager sends this structure to a driver that registered a callback routine for notification of EventCategoryDeviceInterfaceChange events.
