The USB host controllers are usb devices you have plugged into your computer. Windows keeps them in device manager so when you plug them into the computer windows automatically loads the device drivers for them. Every host controller has a root hub simply because that is the design for USB. Root hub's just mean they have access to all files on the computer. Any USB device that is still plugged into the computer will have a named controller in device manager.
