Thinkpad Dock on Non-Thinkpad laptop

I'm trying to set up a Thinkpad Dock to work with my Dell XPS 15 9560. I can charge the laptop through the power delivery from the hub, but nothing else works. I've updated my Dell firmware, ran

sudo pacman -Syu

, and tried both none and user device authentication settings in the BIOS. The dock light glows amber, meaning it is on and has power, but does not detect that it is connected to a computer.

When trying to use tbt:

$ tbtadm devices
Exception: boost::filesystem::directory_iterator::construct: No such file or directory: "/sys/bus/thunderbolt/devices"

Output from

journalctl -f

when I unplug the dock:

$ journalctl -f
xhci_hcd 0000:3e:00.0: xHCI host controller not responding, assume dead
Feb 15 18:40:33 finally kernel: xhci_hcd 0000:3e:00.0: HC died; cleaning up

Feb 15 18:40:33 finally kernel: xhci_hcd 0000:3e:00.0: Host not accessible, reset failed.

Output from

journalctl -f

when I PLUG IN the dock:

$ journalctl -f

I'm not a hardware expert, but I feel like there is a step I am missing on setting up a thunderbolt 3 dock. Any help/guidance is greatly appreciated. In particular, it seems that the tbt error,

No such file or directory: "/sys/bus/thunderbolt/devices"

is of particular importance, but I'm not sure where to go from here.
