Hi Brad,
http://www.trendware.com/products/USB/ptu700730.htm
makes me think that the 3 additional ports on the 10-port
hub are NOT USB. (See the graphic -- increase its size.)
So I called them. The other 3 ports are mouse, keyboard,
and [9-pin ?] serial according to them.
They also have some non-USB Linux driver support, as a .exe
file.
