So - Thank you, Udo and Wim.

I tried several USB2 thumb drives and USB2 hard drives, and they all worked.  I only have one USB3 device, and it doesn't work, even though the machine itself has USB2 and therefore USB3 isn't being used.  So I think most likely the correct explanation is as Udo said.  Most likely the USB3 thumb drive itself doesn't do good USB2 backward compatibility.  So anybody out there reading this - 

Either get the fastest USB2 device you can find, or get an assortment of USB3 devices so you can hopefully find one that's backward compatible USB2.  

The non-bootable USB3 devices I have which don't work:  Mushkin Atom  MKNUFDAM32GB
