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.
