This has started happening several times today. Lasting for 20 seconds or so, the keyboard and touchpad on my Macbook Pro stop responding to inputs. Everything else is working fine and I can see movement on my screen. I'm running the latest Mountain Lion, and I think this may have something to do with it:

this particular log entry doesn't seem to have to do with your problem; it is related to Spotlight and I have these same messages without my keyboard freezing. can you post more logs entries? –  Ethan Lee Oct 1 '12 at 4:24
    
I've posted a more complete log of what happened during that issue, but I suspect there are too many suspects to choose from. –  Aram Kocharyan Oct 1 '12 at 13:45
    
Which model MacBook Pro? 2010? MacBookPro5,2 here. –  Graham Perrin Nov 1 '12 at 9:05

The accepted answer to Timeouts in AppleUSBEHCI - how can I find out what is causing this? may help you to identify devices affected by timeouts. –  Graham Perrin Mar 17 '13 at 13:35

1 Answer 1

This happened to my older MacBook Pro a few years back. The likely culprit isn't software (though you could try using an external keyboard/mouse and attempt to reproduce) but hardware. The top case's USB connection is likely failing.
