 * Name: usbhost_findclass
 *
 * Description:
 *   Find a USB host class implementation previously registered by
 *   usbhost_registerclass().  On success, an instance of struct
 *   usbhost_registry_s will be returned.  That instance will contain all of
 *   the information that will be needed to obtain and bind a struct
 *   usbhost_class_s instance for the device.
 *
 * Input Parameters:
 *   id - Identifies the USB device class that has connect to the USB host.
 *
 * Returned Values:
 *   On success this function will return a non-NULL instance of struct
 *   usbhost_registry_s.  NULL will be returned on failure.  This function
 *   can only fail if (1) id is NULL, or (2) no USB host class is registered
 *   that matches the device class ID.
