USB 2.0 Structure

OS = XP Pro SP3

I have 3 HDDs internal - 3 partitions, 9 HDDs external (USB 2.0)- 11 partitions.
:confused:Examining Computer Management - Device Manager- Universal Serial Bus controllers
I find listed:
6 Generic USB Hubs
4 USB Universal Host Controllers
1 USB2 Enhanced Host Controller
2 USB Composite Devices
11 USB Mass Storage Devices
5 USB Root Hubs
Can anyone tell me what the USB hardware structure looks like?
How do the Generic hubs and Root hubs relate?
I assume the 11 USB Mass Storage Devices are my 11 partitions, correct?
How can I tell?

Thanks
