My wired mouse, wireless mouse, a wired keyboard - all over USB - are freezing every once in a while for a few seconds. Nothing shows up in the logs when this happens and the laptops touchpad and keyboard is still working fine while the USB devices are frozen.

How can I fix this?

Dell Latitude E7470, Ubuntu 17.04, kernel 4.9.45-040945 (I can't use later ones).

Try this command, it is a temporary solution:

sudo sh -c "echo -1 > /sys/module/usbcore/parameters/autosuspend"

I found it on Keyboard stops working Ubuntu 16.04

I have the exact same problem! On Ubuntu 16.04 and kernel 4.13.0-36-generic. the post is here: External usb mouse and keyboard stop working all of a sudden

I haven't found a solution, I tried some things but nothing happened.

Could it be a problem with the Enablement Stacks in Ubuntu 16.04? http://ubuntuhandbook.org/index.php/2017/02/install-remove-enablement-stacks-ubuntu-16-04/

check this : Keyboard and mouse unresponsive after suspend

what I do is suspend the system, then turn-it on and the problem disappears. However after a while it appears again, so I am suspending again...this is frustrating

This one solved the problem permanently for me: How can I disable USB autosuspend on Ubuntu 18.04?
