Evidently USB wakeup does _not_ work on your system when the controller isn't in D3 -- and the system crashes during suspend if the controller _is_ in D3! (Does anybody know if USB wakeup works on these machines under Windows?) What about runtime wakeup? You can test it easily enough. Write "auto" to the power/control attribute for the two controllers. This should cause the controllers (or at least one of them) to go into runtime suspend. Does it then wake up when you plug in a USB device?
