Usb Ports Have Completely Stopped Working

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?

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.

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.
