Ben,

Thanks for the reply.  The web page at actiontec, which i read after 
buying, says this:

    "the Adapter plugs into an external USB port on your desktop or
     notebook (a PC running Windows XP or Vista). Since all of the
     drivers sit directly on the adapter"

Surely it is closed source, but, it is using a driver that is in modern 
Linux kernels and does recognize the vendor and product IDs.  My chances 
should be high.
