for #1 you need to determine if your head switch supports vlans.  Then if
you create a vlan for each port that a hub is plugged into then each hub
would be its own network.  But in the absence of routing of some kind, I
don't see the benefit.  I guess you could use any remaining ports on the
head switch for host systems and you could move them into different vlans as
needed

for #2 the duplex setting on both switches should match, so if switch A only
supports half duplex then switch B should be set for half also.

Need a suggestion.

1. Can this be done.. logically segment the network by assigning VLANs to
the switch ports that the 5 hubs (existing hardware) are connected to a
switch. Cost is also an issue here.
2. Switch A, port speed can only be set to half duplex for either 10 or 100
Mbps, a known issue with this particular hardware and the client is not able
to change it even with the manufacturers recommendation.  Switch B, is a new
switch that is configurable to go half or full duplex on the port speed.
Switch B is uplinked to switch A. Switch B's port speed is set at 100 Full
duplex with autonegotiation turned off.  The connectivity is slow, should
the port speed on switch B change to half duplex as it is on switch A until
the problem with the port speed on switch A is fixed.
