The center of the first tier is always the controller/hub in the computer. This means that up
to five levels of USB hubs can be added. The last tier (tier seven) does only allow
functions (devices) in it.

Figure 6 - USB Bus Topology

USB  2.0  host  controllers  and  hubs  provide  capabilities  so  that  full-speed  and  low-speed
data  can  be  transmitted  at  high-speed  between  the  host  controller  and  the  hub,  but
transmitted  between  the  hub  and  the  device  at  full-speed  or  low-speed.  This  capability
minimizes  the  impact  that  full-speed  and  low-speed  devices  have  upon  the  bandwidth
available for high-speed devices.
