I've found another issue that might be related.. once in awhile the keyboard goes dead.
So I tried switching usb ports , doesn't help.

I found this script which seems to reset the usb , and it does end up working again.. :

#!/bin/bash

if [[ $EUID != 0 ]] ; then
  echo This must be run as root!
  exit 1
fi

for xhci in /sys/bus/pci/drivers/?hci_hcd ; do

  if ! cd $xhci ; then
    echo Weird error. Failed to change directory to $xhci
    exit 1
  fi

  echo Resetting devices from $xhci...

  for i in ????:??:??.? ; do
    echo -n "$i" > unbind
    echo -n "$i" > bind
  done
done

Seems to work ok, I guess its just spam then?
Tried wiggling the cable, disconnect and reconnect.. I'll see if that helps anything.

Do you actually have any problems with the keyboard apart from the dmesg spam?

Could be a dodgy cable and/or connector.

I keep getting this message repeating again and again.. in dmesg -wH

Should I use a different keyboard?
