Hello,
The USB device's registers (if any) are unrelated to the PCI bus' configuration registers. The term "host bus bridges" refers to a PCI element, not USB.
A USB hub can communicate with the host using a PCI/PCIe bus, but there's a complete distinction between the registers used to configure the USB hub as a PCI device and those possibly used to configure an endpoint on the USB bus.
To get an idea of the PCI registers, take a look on this:
