Indeed, this is not addressed, though it may sense to have a way in the device model to call the suspend/resume callbacks of "childs" of a given hub only for that purpose, I don't think this is implemented yet. Maybe talk to Patrick about it. In general "local" power management (automatic disk spin down, chipset idle-pm, etc...) is ... local to the driver, though you can probably use the power state field of struct device to store your current state if it maps to those semantics.
