USB ports not working on Gigabyte 990XA-UD3
I'm trying to install Linux (Manjaro) on a computer with a Gigabyte 990XA-UD3 motherboard and I'm having issues with USB ports. They work fine in the BIOS setup utility (and they worked fine on Windows 7, which was previously installed on that computer), but during the boot of the live image, all USB ports shut down, except USB 3, with errors: "unable to enumerate USB device".
I tried tweaking the BIOS settings regarding USB peripherals, but to no luck. I tried enabling IOMMU, disabling IOMMU, turning on/off legacy USB support, XHCI/ECHI hand-off mode...
I've even completed a vanilla Arch install (no DE, just TTY, had to burn it to a DVD, because it would not boot from a USB media) thinking it might be a software issue, but the problem still persists: just seconds into boot all USB 1 & 2 ports die. I can only use a keyboard if I plug it into a USB 3 port.
I looked into whether it is possible to update the firmware on the motherboard, but it seems I already have the latest and only version ("FD" from 2013).
Is there any hope to get Linux running well on this PC? Could anyone help me troubleshoot it? Or should I just trash it?

I suggest that you also try a non-Arch version of Linux to confirm if this is an Arch or a Linux issue. It is unlikely to be the former, but it's always worth narrowing down the possibilities.

It's definitely not distro-specific. Just tried it with Ubuntu, it's exactly the same as with Manjaro. As the live image boots from a DVD, all USB devices not on USB 3 shut down.
Please, if you have any other idea, I'll try anything (within reason, or course).

I've searched on many different forums and websites, and found a lot of posts from around 2013 about this motherboard (when it was new), about people having trouble installing from USB storage. That's why I burnt the ISO images to DVDs, just so that the live image successfully boots up. But nothing in any of the similar threads I've seen so far has anything useful that could solve this problem.
I'm starting to doubt that the solution exist, and starting to believe that this motherboard is Windows only (of course, this is never explicitly mentioned by the manufacturer).

If you connect a USB hub to the USB 3 port for all your USB devices, could you not use it that way?

Kekmose,
No guarantees but try this:
Go into BIOS and enable XHCI handoff, enable EHCI handoff, enable IOMMU, then save and boot into Manjaro.
Edit /boot/grub/grub.cfg and insert kernel parameter iommu=soft. Go to the kernel (linux) line and insert iommu=soft before the parameter quiet or splash.
Code:
GRUB_CMDLINE_LINUX_DEFAULT="quiet iommu=soft plus_lots_more"
Save the file and reboot.
To make the change permanent, also include the parameter iommu=soft in the /etc/default/grub file.
Code:
sudo gedit /etc/default/grub
Reboot.
