Are your USB ports USB 2.0? Canon lbp 6030 driver. It is a common design for USB 2.0 ports to be managed by two controllers: one for low speed and full speed (the USB 1.1 speeds), and one for high speed (the new speed available beginning with USB 2.0). If this is the case, the 3rd root hub is probably from the EHCI controller managing the high speed connections, and the 1st and 2nd root hubs are probably from a pair of OHCI or UHCI controllers managing the low and full speed connections. Each USB port on your computer would then be connected to two of the controllers, the EHCI controller and one of the other two controllers, and which one is used would depend on the speed chosen by the USB device connected to that port.
