I got a new laptop (ThinkPad X1 Carbon) but it only has one USB-C port. I also have a USB-C portable monitor (Asus ZenScreen) that gets its power and data through the single port USB-C connection to the laptop.
So now I have both devices sucking battery life with no way for me to provide external power.
There are plenty of USB-C hubs that can pass power through to the laptop, while also providing signal output, though it seems only to full VGA, HDMI, DisplayPort outputs, none that have USB-C output....
Is this a limitation of the USB specification?
Or is it a rare use-case and not enough vendors out there building such hubs?
