dmesg ought to show a similar error.  The kernel is trying to read whatever is 
hanging off your ehci-pci port 3 and it times out.  The error message means 
"Timeout expired before the transfer completed".  It could be a problematic 
device controller, or power demands of the device exceed what the MoBo 
supplies.

I've seen the same on USB 3.0 sticks which failed soon after, so you may want 
to back up your data in the first instance.
