Interesting. I checked the USB roothub's usbN/power/wakeup file, and it was marked as enabled. However, the PCI device's power/wakeup file was marked as disabled. Any idea why it would be disabled by default? I do notice that when I enable the PCI USB roothub remote wake for the second EHCI host controller in the system (PCI device 00:1a.7), the system will immediately pop out of suspend, even though there's no USB devices attached. All the other host controllers on this system seem to work properly, except for the NEC host controller add-in card, which I can't get to wake the system up at all. Perhaps the PCI developers disabled remote wake for all Intel PCI USB hosts because of that?
