Use whatever text editor to edit the following file as root:
/etc/default/grub
The editor will open showing you the contents of grub configuration file. Search for this line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
Change the line by adding iommu=soft and now the line will look like this:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash iommu=soft"
Save the file and exit text editor.
Now, type to the terminal:
sudo update-grub
Finally, reboot your PC and the recommended change takes effect. Hopefully all your USB 3 ports are working now.
Besides the recommendation you were seeking help on I would look in your BIOS and carefully examine all USB related options.
