  58  * The configuration structures refer to the USB Configurations that will be
  59  * made available to a USB HOST during the enumeration process.
  60  *
  61  * The USB HOST will select a configuration and optionally an interface with
  62  * the usb set configuration and set interface commands.
  63  *
  64  * The selected interface (or the default interface if not specifically
  65  * selected) will define the list of endpoints that will be used.
  66  *
  67  * The configuration and interfaces are stored in an array that is indexed
  68  * by the specified configuratin or interface number minus one.
  69  *
  70  * A configuration number of zero is used to specify a return to the unconfigured
  71  * state.
