USB ports have completely stopped working

Question

Every USB port has stopped working on my laptop running Ubuntu 16.04 LTS. I executed lsusb in terminal and was prompted with the following:

Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

I'm not sure what I'm doing. How can I fix this?

Have a look in the BIOS / set-up, sometimes there is an option to disable USB ports - make sure it's off. — Jonas Czech, Sep 13 '16 at 16:11
What's the output of `lspci -nnk | grep -A2 USB` and `sudo dmesg | grep -i -e '[uoex]hci' -e usb`? See [How do I save terminal output to a file?](//askubuntu.com/q/420981/175814) if you don't know how. And could you please [edit] your post, when you want to add information? Especially file or program output [listings](/editing-help#code) (with the help of the `{}` button in the editor toolbar) are much more readable there; alternatively you can use a [pastie service](//paste.ubuntu.com/) for longer listings and include the link of your pastie in your question. — David Foerster, Sep 13 '16 at 17:10

Maybe it will help you:
Open terminal, type:

sudo -H gedit /etc/default/grub

Change the line

GRUB_CMDLINE_LINUX=""

To

GRUB_CMDLINE_LINUX="acpi=force irqpoll"

Save and close the file.

sudo update-grub

Reboot.

Thanks bro, you saved me. I'd already pictured myself reinstalling the whole system. – Tobias Feil Apr 03 '20 at 10:46
This solution didn't work for me on Ubuntu 20.04 LTS, but i have tried Step number (4) in this link (https://www.makeuseof.com/tag/fix-usb-device-port-linux/) and works fine with me. – Ahmed Mousa Jun 21 '20 at 10:47

Legend! This had been bugging me for ages. Your fix worked perfectly! Cheers. – compuphys Jul 19 '22 at 21:25
@AhmedMousa, your step (4) is "reboot". Writing it out saves people time. – Martian2020 Feb 22 '23 at 03:43

For GIGABYTE-970A-UD3P I had to do something similar what ozcyto recommended in this thread:

sudo nano /etc/default/grub

Change GRUB_CMDLINE_LINUX line to:

GRUB_CMDLINE_LINUX="iommu=soft"

Then (preferably in a new terminal window) run this:

sudo update-grub

Restart your PC and it should work.
