I have a laptop HP HP ENVY x360 Convertible/81AD, BIOS F.23 12/28/2016 and I would like to have USB C supported (especially charging and display). I bought a Kensington USB-C Universal Dock 60W SD4600P. When connecting I get only all of the standard USB features (HUB, Ethernet, soundcard) - no charging, no external displays detected.

I've built mainline kernel 4.12.14 myself. Which options am I missing (or is USB C fully supported as of today)?

Thank you

This helped a little. I have added PCI hotplugging and all possible Intel drivers.

When I plug in the dock I get (there is also a keyboard and trackball connected to it):

It is still detecting it as a regular hub. External display is not working thru the dock.

I have run lshw and the only unclaimed driver left is:
Code:

 *-power UNCLAIMED

       vendor: OEM Define 2

Kensington USB-C Universal Dock 60W SD4600P as mentioned in the first post. Dock works fine on Windows with an external screen.
