I have an Asrock Z68 Extreme4 motherboard that has 2 USB 3.0 ports at the rear. My external WD My Book 4TB USB 3.0 Hard drive will not operate at USB 3.0 speeds no matter what I do. Using USB Device Tree Viewer (which actually shows I have 8 USB 3.0 ports....hmmm), it always shows my external HD as "high-speed" using USB Version 2.10 and not "SuperSpeed" using USB version 3.00. I have a 32GB USB memory stick which inside USB Device Tree Viewer, shows it as "SuperSpeed" most of the time but frustratingly, sometimes this will only show as "high-speed" when plugged into either one of the two USB 3.0 ports. Sometimes I have to reboot my computer for my memory stick to operate at USB 3 speeds. As I said, I can never get my external HD to operate at SuperSpeed. This leads me to believe that it's not the fault of my external HD but something else.
I have installed Etron EJ168 USB 3.0 Host Controller drivers 0.115 and now 0.118 hoping it solves my problem. I have also disabled legacy USB 3.0 support in the UEFI (BIOS) and set legacy USB support to UEFI only. Power saving features of the USB ports are off too. Nothing is working, any ideas? I have attached two pictures to this thread for you to look at:
