Hi Sarah, watching your talk and drinking tea I had an idea. Switching off ports saves power in itself. It also allows switching off host controllers. The problem with switching off power on external ports is that they don't detect hotplug events anymore. So is there a way to switch off controllers and leave ports on, saving at least some power? And it seems to me that in many cases, namely EHCI with companion controllers and XHCI controllers that implement a vendor specific switching option, we could switch the ports so that a minimum number of controllers is connected to ports that are not switched off. What do you think?
