The following steps / troubleshooting has been performed:

I am not the first and only to experience this bug.
Many other users of this motherboard who choose to use Ubuntu as their primary operating system encounter this bug- however, I appear to be the first to go through the effort of initiating a ticket.
Please help.
Thank you.

In Ubuntu 15.10 the bug is still present.
I found a workaround: http://askubuntu.com/questions/602791/msi-970-gaming-usb-3-0-drivers

"I had the same problem. Resolved it by adding in /etc/default/grub

GRUB_CMDLINE_LINUX="iommu=soft"
Then sudo update-grub, reboot and voilà!"

... I do not know what iommu is and if it can disable something important, may be someone can tell us about it?

Hello Tommy_CZ,

The workaround you provided was a success.
I was able to mount a USB 3.0 device and validated approximately 2x the data transmission speed.
So USB 3.0 is now working for me.

Thank you for your support as I had nearly accepted the fate of using USB 2.0 on this machine, and this is great.

I have no idea why: [GRUB_CMDLINE_LINUX="iommu=soft"] solves the problem- or what 'iommu=soft' represents either.
I would like to know more about it or find a more permanent solution.

Thanks again--

Works for me but pretty sure I am still at USB 2.0 speeds.

I am not sure how to help in your scenario. When I made the setting adjustment I was not only able to use the existing USB 3.0 port, I was able to get the USB 3.0 speeds. Did you validate zero transfer speed difference between a USB 2.0 versus a USB 3.0 device? Is there anything else you need to enable or configure on your machine to enable USB 3.0 specifically?

Regards,

For those of you wondering what iommu=soft is:

https://www.kernel.org/doc/Documentation/x86/x86_64/boot-options.txt

AMD64 specific boot options

IOMMU (input/output memory management unit)

 General iommu options:
    off Don't initialize and use any kind of IOMMU.
    noforce Don't force hardware IOMMU usage when it is not needed.
                       (default).
    force Force the use of the hardware IOMMU even when it is
                       not actually needed (e.g. because < 3 GB memory).
    soft Use software bounce buffering (SWIOTLB) (default for
                       Intel machines). This can be used to prevent the usage
                       of an available hardware IOMMU.

I used the workaround above and it worked.

And of course in Ubuntu 16.04.1 the bug is still here, plus from now my internal USB3 connection (to SD card reader) stopped to work.

Sometimes it seems whole Ubuntu is falling apart without reason.

Enabling "IOMMU Mode" in the bios "Overclocking/CPU Features" setion fixed it for me.
