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