If you are using a non-crossover cable, you should connect an 'uplink' port
on one of the hubs to a standard port on the other.

Also, many hubs which are specified as "N-port + uplink" are actually N-port
hubs, with the uplink port shared with a standard port (i.e. the standard
and uplink ports are wired in parallel, and the uplink port wired in
crossover configuration. Try unplugging each of your machines from Hub B
in turn, and see if the network magically springs to life.
