Problem keyboard not working

Hello,

I have a raspberry pi I updated it to Kodi 17
from that moment my usb connected keyboard is not working anymore
if I connect a different keyboard that works
if I connect my usb keyboard to a different pc it works

if I check the log file i get the following warnings:
