Notification when a USB device is attached to or detached from the virtual USB controller.
This notification is sent as a result of the indirect request to attach the device because it matches one of the machine USB filters, or as a result of the direct request issued by @link IConsole::attachUSBDevice IConsole::attachUSBDevice@endlink<b></b> or @link IConsole::detachUSBDevice IConsole::detachUSBDevice@endlink<b></b>. This notification is sent in case of both a succeeded and a failed request completion. When the request succeeds, the @a error parameter is @c null, and the given device has been already added to (when @a attached is @c true) or removed from (when @a attached is @c false) the collection represented by @link IConsole::USBDevices IConsole::USBDevices@endlink<b></b>. On failure, the collection doesn't change and the @a error parameter represents the error message describing the failure.
