I don't have much exposure to USB subsystem. 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? Alan Stern
