+ * Name: usbhost_create
+ *
+ * Description:
+ *   This function implements the create() method of struct usb_registry_s. 
+ *   The create() method is a callback into the class implementation.  It is
+ *   used to (1) create a new instance of the USB host class state and to (2)
+ *   bind a USB host driver "session" to the class instance.  Use of this
+ *   create() method will support environments where there may be multiple
+ *   USB ports and multiple USB devices simultaneously connected.
+ *
+ * Input Parameters:
+ *   drvr - An instance of struct usbhost_driver_s that the class
+ *     implementation will "bind" to its state structure and will
+ *     subsequently use to communicate with the USB host driver.
+ *
+ * Returned Values:
+ *   On success, this function will return a non-NULL instance of struct
+ *   usbhost_class_s that can be used by the USB host driver to communicate
+ *   with the USB host class.  NULL is returned on failure; this function
+ *   will fail only if the drvr input parameter is NULL or if there are
+ *   insufficient resources to create another USB host class instance.
