The hub will send the packets to all devices connected including the
originating device.

can you give a reference for that?

I will give a reference for what I said, which is that the hub sends to
all except the original device

p.60 "The hub's internal wiring propagates the signal to all other
ports, but not back to the port that the signal was received on"

I'm a little uncertain about your level of understanding but you can start here: http://compnetworking.about.com/od/hardwarenetworkgear/l/aa012801a.htm
The text you quote is an excellent book on networking but assumes you can get the nuances.
