How can I restore USB 2.0 Functionality after upgrade to Ubuntu 18.10?
I recently upgraded to 18.10, and now only my USB 3.0 ports seem to work. My motherboard's USB 2.0 ports work well in windows still, and dmesg shows that the ports are still detected.
Here's a diff of dmesg before and after a USB thumb drive is plugged in to the non-working port.

This is consistent across my webcam, mouse and USB drives. My motherboard is a GIGABYTE GA-990FXA-UD3, and I've fiddled with settings in the BIOS about workarounds for legacy USB devices, but it didn't seem to have any effect.
How might I approach getting my usb ports back? If this is a bug, where would I submit a bug report.
Happy to provide any other information necessary.

- In the BIOS, set IOMMU to "Enabled"
That got the USB 2.0 ports working, but now the USB 3.0 ports don't work.
In the BIOS, check the USB setting. It should probably be set to "legacy", but if it's already set that way, try another setting, and see if the USB 3.0 ports work again.
In the
terminal...
sudo -H gedit /etc/default/grub
input your password
then find the line that says: GRUB_CMDLINE_LINUX=""
then make it this: GRUB_CMDLINE_LINUX="iommu=soft"
save the file
then run this in the terminal...
sudo update-grub
reboot
During the reboot, bring up the BIOS settings, and disable the IOMMU setting that we enabled in step #1.

Check the web site for BIOS updates (there are a few). You'll have to know what revision MB you have... Rev 1.0 or Rev 4.0, or something else... to get the correct BIOS updater.

Boot to the Ubuntu Live 18.10 DVD/USB and check if your USB 2.0 ports are working.
