+ * FIXME: docs
+ * FIXME: there are issues here on how BEACON and SCAN on USB RCI deal
+ *        with each other. Currently seems that START_BEACON while
+ *        SCAN_ONLY will cancel the scan, so we need to update the
+ *        state here. Clarification request sent by email on
+ *        10/05/2005.
+ *        10/28/2005 No clear answer heard--maybe we'll hack the API
+ *                   so that when we start beaconing, if the HC is
+ *                   scanning in a mode not compatible with beaconing
+ *                   we just fail.
