My 7-port hubs are fine, but not my multifunction gizmos.  I have a PR in on
this.  Symptoms are:
1.  USB devices attached when the multifunction hub is connected are probed.
No changes are ever detected, though - unplugging them or plugging them back
in doesn't work.
2.  PS/2 ports on the ones that have PS/2 ports are very, very, weird - they
send a key press every 1/4 second, like clockwork, from their buffer.

I've got three devices which do this, by different vendors - but two, at
least, are using the same chipset.
