In spite of its name, USB is not a bus.  At the physical level, it is 
most definitely point to point, and, unlike RS232 cannot be abused into 
a bus configuration.

It does have a network layer, although I think that only supports 
unicast.  RS232 is only a physical layer specification, and not a 
complete one.  Anyone using the internet before ADSL almost certainly 
was using RS232 as the first hop to a global network.
