"touchy" about communicating

[Mikus Grinbergs]

Don't have wireless at home.  Do have enough external devices 
plugged in to need an USB hub (separately powered).

Had two XOs set up identically - with the ethernet adapter connected 
at the hub (so adapter power is supplied even when the XO suspends). 
  The first XO connected fine to the wired ethernet.  The second XO 
would not see the ethernet.

At that second XO, swapped two cable positions - plugged the 
keyboard in to the hub and plugged the ethernet adapter directly in 
to the XO.  Now that second XO saw the ethernet.   Go figure.
