Hi Alan and Rafael, Is there a reason why runtime PM is disabled by default for PCI USB host controllers? It would really be nice to have this turned on by default at boot, rather than running udev scripts or powertop. Are there PCI USB hosts that can't handle D3? Or something else preventing us from turning runtime PM on by default?
