Recently I purchased an Antec 902 V3 case. It was advertised as having 2 front panel USB 2.0 ports and 1 front panel USB 3.0 port. Indeed if you go to the Antec web site that is what is advertised. When I received mine I realized that I had 3 USB 3.0 ports, and two cables (one split into 2 for the third port) coming from the front panel, but only with 20 pin connectors. My MB does not have and USB 3.0 headers. I have 2 USB 3.0 connections on the back of my MB. SOoooo, I purchased 2 USB 3.0 cables, 2 USB 3.0 Box Header 20pin to Box Header 20pin Male Adapters http://www.monoprice.com/products/product.asp?c_id=104&cp_id=10314&cs_id=1031403&p_id=8167&seq=1&format=2, and 2 of these Bitfenix connectors: http://www.microcenter.com/single_product_results.phtml?product_id=0371734. I hooked it all up and get no connection to the front panel connectors. I can only confirm that the USB 3.0 cables work when plugged into the MB back panel connectors. I also switched out the Bitfenix connectors, and tried these: http://www.amazon.com/gp/product/B005AJX9MW/ref=oh_details_o00_s00_i00 but I still have no connection to the front panel. What can I do?
