I've used the Dell TB docks and Lenovo docks with both Dells and Lenovo notebooks designed for it. NO THANK YOU! I have yet to see a thunderbolt dock provide a reliable enough device for me to recommend for work. To those who praise or recommend the thunderbolt docks. I have the same computers on my network and we use the same docks, we've not seen the issue as yet. Force winders to reload them all, and see if it comes back. Uninstall all usb devices/drivers from Winders (if the above does not work). If any plugged in USB device works (to the dock) then you know the dock is passing data. Start plugging other USB devices into the dock (to see what breaths life) - good examples are mice, keyboards, etc. I second that I'd remove any recent updates, and see if it comes back alive. Yes I've fixed a lot of laptops this way, its weird, and shouldn't work, but it has.

This is going to sound stupid, and shouldn't work, but I've seen flipping the USB-C connector over helps at times.
