    GA-970A-DS3P revision 1 no usb 3.0

    Enabling iommu in the bios will fix the Ethernet issue and make the usb 2.0 ports work for Gigabyte 970 chipset board GA-970A-DS3P rev 1.0, but usb 3.0 ports will no longer work on the back of the motherboard or from the internal 20 pin connector for the front panel. I have tried Ubuntu 12.04 LTS and 14.04 with the same result. If there is anyone else in the same boat please post up.

    Re: GA-970A-DS3P revision 1 no usb 3.0

    Here is my updated fix

    First enable iommu in the uefi by restarting your computer and pressing delete to enter the uefi

    plug your usb mouse, keyboard and thumbdrive in usb 2 ports.

    save and exit the uefi

    Then In Ubuntu:

    press Ctrl+Alt+T to open up a terminal

    run the following command: sudo gedit /etc/default/grub

    Only edit the empty quotes in this line to read: GRUB_CMDLINE_LINUX="iommu=soft"

    save changes to grub and exit gedit and the terminal

    Open up a new terminal with ctrl+alt+t

    run the following command: sudo update-grub

    then exit the terminal using this command: exit

    Restart your computer press delete to get back into the uefi

    Disable iommu in bios, load optimized defaults and restart.

    usb, 2.0 usb 3.0 and networking all work now in Ubuntu, and disabling iommu in bios may also help improve your boot times.

    If the above post helps anyone I am happy.

    Hey Ozcyto!!!

    It also works on the Gigabyte 970A-UD3P motherboard. Fixed both USB 2.0 adn 3.0.

    How did you discover this?? I spent three days trying to figure out what was wrong.

    Thanks a bunch,

    beaucoder2 im glad it worked for you.

    I recently started using the same motherboard gigabyte ud3p and the fix worked for me as well. I figured Iommu was correcting the same problem with uefi and other board brands so i figured i would try using a software iommu instead of hardware iommu and it worked.

    OMFG !

    Thank you sooo so much, i mean, i spent sooo much time on figuring out what the problem was with my system. First the LAN was not working, so after a bit of research i turned on the IOMMU-controller and then the usb3-ports weren't working. And then i found your post. OMG thank you soo much, you made my day. BTW how the f... did you figure this out, i mean really, how?
