No one that have any comments on this? Haavard is it possible to get this upstream? The patch allows the USB driver to be active and when the USB bus is disconnected (with reversed signaling). I observe a drop in power consumption of 150mW, and for people dependent on battery that is a lot. And in our design we need to have this pin inverted.
