The additional test for ep->ovflist != EP_UNACTIVE_PTR to signify available events was added in 5071f97ec6d74f006072de0ce89b67c8792fe5a1 but doesn't appear to do anything. Either this is a bug or the check isn't needed. If the ep->ovflist is not EP_UNACTIVE_PTR then ep_send_events() calls ep_scan_ready_list() which sets ep->ovflist = NULL thus loosing any events which may have been stored there.
