Hi there!
After wasting countless hours trying to get USB 3.0 working, the time has come to give up. I would say that I have devoted 100 hours to trying to get it to work, without success. It would seem that it is a battle that I cannot win and I can't waste no more time on it. I guess I just have to pursue other options.
I built my system back in March. The motherboard is GA-X58-USB3 with Intel i7 960 CPU. I have 18GB Corsair Vengeance RAM and a Nvidia GeForce Gt 440 1GB graphics card. My system was purpose built for running Adobe photoshop. USB 3.0 was part of the decision process as I need it to back up my extensive catalogue of images to external removable drives.
Unfortunately I am unable to get USB 3.0 to work. I initially purchased a USB 3.0 dual docking station and after frustratingly trying to get it to work for 3 days, returned it for refund. I experienced two problems. Sometimes it would connect to USB 3.0 but after 1-2 minutes would disconnect. Other times it would try to connect and then a message would pop up stating that the drives needed to be formatted. Everything however worked fine when connected to USB 2.0 and USB 2.0 devices worked fine when connected to the USB 3.0 ports. Through all of this, I updated motherboard Bios, did a firmware update to the NEC bios and updated drivers to latest versions. Nothing changed.
After a few months of seeking an alternative backup solution I purchased another brand of USB 3.0 docking station after reading about known problems with the Vantec unit previously purchased. Once again I experienced the same problem. I contacted Gigabyte and was instructed to flash the motherboard bios to latest version. I now have the newest motherboard bios, NEC controller bios and drivers and I still cannot get USB 3.0 to work. It now just comes up with a message stating that the drives need to be formatted. As before, the docking station and drives are working fine in USB 2.0 and USB 2.0 devices are working fine in the USB 3.0 ports. The do not need to be reformatted.
In addition to everything above, I also tried a USB 3.0 add-on card. It too had an NEC controller and exhibits exactly the same problems.
Motherboard bios version - f5a
NEC Driver version - 2.1.19.0
NEC Firmware Version - 3.0.2.8.0.8
Anyway, not knowing what more I can do, I thought I would post my ongoing problem here in hope that someone can offer a solution. Otherwise, I have no option but to consider alternative solutions, which may involve another brand mother board.
Cheers, Malf
