I don't think this is such a good approach. There are places in ehci-hcd where port power is toggled directly, without going through ehci_hub_control(). For example, see ehci_turn_off_all_ports(). You should do what I recommended earlier: Add routines to ehci-hcd specifically for turning port power on or off, and then use those routines every place the power setting gets changed. Then those routines can call a platform-specific override, if needed.
