When I first bought my Yoga 910, I also bought a USB-C j5 Create hub that has one USB-C, two USB-3, HDMI and Ethernet. I was able to plug this hub into the second USB-C port on my laptop (the one for video, not power) and use it without any external power. I was able to use the hub to play video on a TV via the HDMI adapter. However, after an update at some point, that changed. Now if I don't supply power to the hub, it is not even recognized by my laptop and attached devices (including the TV) do not work.
Also, the power USB-C port doesn't support data of any kind, meaning it is only good for plugging my power adapter into. I thought at one time I could use it as a USB hub.
Is there a setting to change how these ports operate? The USB-C port should supply enough power to the hub to operate "normal" devices like a phone or a memory card adapter. I should not need external power to operate it.
