Thanks Ian.  I hadn't noticed the hbeat.basic schema reference in the
logged messages below.

Given the comment above about use of the additional port and remote-ip
to allow pc hubs to operate, does this imply that devices that send out
hbeat.basic messages cannot be supported by a hub?  If not, how should
the hub determine the appropriate port to forward messages to?
