So I bought a K55 a while ago and Im having similar issues with errors in the log. My system comes to a crawl when gaming with this keyboard. When I unplug it and use my older keyboard, everything goes back to normal. Took me 2 days to figure out it was the keyboard causing issues.
I get similar issues as this post: http://forum.corsair.com/forums/showpost.php?p=954994&postcount=7
