Hi forum.

You can find my system specs on my profile.
My issue : Right so I am not ignorant of PCs at all but this is vexing me. Some of my USB 3 ports are totally unresponsive. They provide power but nothing else. As far as I can tell the ports giving issues are all ASMedia third party controlled. The ports are unresponsive to any and all USB devices I have tried.(mouse, multiple drives USB2 and 3, flash drives, etc.)

What I have tried :
Latest BIOS update (among other things improves USB compatibility)
Latest ASMedia and Intel USB drivers after uninstal and clean sweep.

Now I am almost to the point of going for a fresh windows install but would like to avoid it for now as the installation is barely 3 months old and quite well maintained otherwise.
I have googled this as well and have found many people with similar issues but none of the solutions have helped.

Can anyone help?

Hi, It might be a controller issue. Is it enabled in BIOS? If yes and still no go, I would RMA the board.

Ok it seems it is fixed FOR NOW, I have found this very intermittent...
I have disable USB legacy support and uninstalled ASRock FastUSB.

Either one by itself made no difference but together it worked...

So strange, although I am pretty sure this will happen again.

If it does I will resort to a fresh install just to be sure before I RMA.

I did both as directed. FastUSB does provide a small boost to transfer speeds, especially when streaming.
