Split the attach/detach events up into device, driver and controller
attach and detach events.
The commit message from NetBSD was:
date: 2000/02/02 07:34:00; author: augustss; state: Exp;
Change the USB event mechanism to include more information
about devices and drivers. Partly from FreeBSD.
Also rework usbd to take these new event types into account.
