I recently upgraded to Ubuntu 18.10 (Cosmic Cuttlefish), 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 into the non-working port:

And a diff of dmesg before and after the same USB thumb drive is plugged into a working USB 3.0 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?

  • 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. – heynnema Jan 21 '19 at 19:05
  • Just checked, I'm currently running the most updated version of the BIOS. – Riet Jan 21 '19 at 21:39
  • Boot to the Ubuntu Live 18.10 DVD/USB and check if your USB 2.0 ports are working. – heynnema Jan 21 '19 at 21:46
  • They do not work on the live USB. They worked in 16.04, and work in windows, though. – Riet Jan 21 '19 at 21:48
  • In the BIOS, set IOMMU to "Enabled" and recheck. – heynnema Jan 21 '19 at 21:49
  • Done. Now the 2.0 ports work, but the 3.0 don't. – Riet Jan 21 '19 at 21:55
  • In the BIOS, check the USB setting. It should probably be set to "legacy", but if it's already that way, try another selection, and see if the USB 3.0 ports work. – heynnema Jan 21 '19 at 21:57

  1. In the BIOS, set IOMMU to "Enabled"

    That gets the USB 2.0 ports working, but now the USB 3.0 ports don't work.

  2. 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.

  3. 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

  • I forgot about that setting! Thanks! in order to properly work, the IOMMU setting must be enabled, as well as the CMDLINE argument being set with "iommu=soft" – Riet Jan 21 '19 at 23:01
