Sounds like the keyboard went idle (on its own!?) and the Rasp lost
connection to it. ep6.1 is the name of a USB device (something about
logical unit devices or something,) you can try unplugging something and
you'll see similar things pop up. kb is complaining the keyboard went away,
and since there is no keyboard, died. You could try ungplugging it and
plugging it in.
