Yes that was what I had mean't to say, it just brought the issue to my 
attention! (I  think - although it might also/alternatively be related 
to trialling mythtv Android Frontend on a Nexus 10?)

Everything is direct connected to the motherboard, a Gigabyte 
GA-Z68X-UD3H-B3

There is no usb hub involved. There is a usb mouse, USB extension cable 
with nothing in its female end, and a usb ir device (hauppauge kit with 
associated RC6 IR remote 1069/335(UK/AU) 
(http://www.mythtv.org/wiki/MCE_Remote)) which suggests to me the issue 
is with this, as the messages refer to lirc. I disabled lirc in the 
mythbuntu control centre, issue seemed to persist. I unplugged the IR 
USB device and messages seem to have stopped now!

messages tail now:
