It's ironic that the generic_subclass thing was added to support 
onboard_usb_dev, after some debate about whether it would be better just 
to export the generic callbacks.  Now you're going to implement the 
alternative solution for onboard_usb_dev, while other drivers continue 
to use generic_subclass.

Oh well, I guess there's nothing wrong with having two ways to do it.
