One example, suitable for PCI devices, can be found in 
drivers/usb/host/ehci-pci.c:ehci_pci_setup().

However the best approach would be for you to avoid adding any
special-purpose code at all.  Is it possible to handle
overcurrent-change events in a way that will work just as well for
normal hubs as for your MSP root hub?
