2015 13" MacBook Pro Trackpad and Keyboard stop working
Since I ran into the same problem and this comes up on Google, I will provide an answer, even if there is no question.


When my keyboard and touchpad stopped working, the power button was still ok.
Resetting NVRAM did not help.
Using an external keyboard and mouse was fine.


Typing sudo dmesg | tail on the command line was showing similar messages:

I brought it to the local Apple support partner. They first tried it by updating the touchpad controller software. Since that did not work either, they changed the HSSPI cable.
