The Etron website would be the last place I would look ,they were still only offering v1.3 drivers 2 months after the v1.5 drivers were available on station drivers . I got those drivers ,and a few months later the exact same drivers were available on the Gigabyte website .
I only posted the link and information ,because I knew that some members had been experiencing problems with USB 3.0.
THE OLD ADDAGE "IF IT AINT BROKE , DONT FIX IT" springs to mind ,but some who are having problems may want to at least try this option .the drivers are still working fine for me , using external USB 3 drives ,pendrives and card readers etc ,without problems .
