I have motherboard GA-Z170X-UD5 TH with 2 USB Type-C (USB 3.1/Thunderbolt 3) ports, BIOS version F20b.
Both ports are "sleeping" on cold start - I can't boot from USB device plugged into any and both of these 2 USB Type-C ports. Ubuntu 17.04 as of December 11 doesn't see anything (no messages in dmesg).
But magically situation changes when involve Windows 10 to the party. I boot into Windows PE based on Windows 10 and it happily see flash drive and my Nexus 6P connected to both ports.
After this without unplugging mentioned devices I reboot into Ubuntu and "magic" - both flash drive and Nexus 6P work fine through these 2 USB Type-C ports. Even though it works in Ubuntu, BIOS still doesn't see anything.

But things are even more interesting: when I unplug either Nexus 6P or flash drive and then plug back - they still work fine! But as soon as I unplug both of them - Ubuntu doesn't see anything and doesn't post anything into dmesg until I boot into Windows 10 again. Interestingly, USB 3.1 controller disappears:
