No, it didn't start happening after update/upgrade because my PC is few
weeks old and I didn't check 3.1 support ever before.
With mainline kernel 4.9.0-040900-lowlatency behavior is exactly the
same

Title:
USB 3.1 controller does weird magic: appears after Windows 10,
disappears otherwise
Status in linux package in Ubuntu:
Confirmed
Bug description:
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:
