Ah HAH! He said. Try temporarily plugging one of the HVR units into the 
box, and leave the other on the hub (dispense with the flirc unit while 
testing). You may now find that both are discovered, which points to a 
problem with the hub.

And check for any more USB plug points on the motherboard. There may be 
a capabiliy of adding more direct ports.
