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. nazar-pc ~ lspci -d ::0c03 -k 00:14.0 USB controller: Intel Corporation Sunrise Point-H USB 3.0 xHCI Controller (rev 31) Subsystem: Gigabyte Technology Co., Ltd Sunrise Point-H USB 3.0 xHCI Controller Kernel driver in use: xhci_hcd 0b:00.0 USB controller: Intel Corporation DSL6540 USB 3.1 Controller [Alpine Ridge] Subsystem: Device 2222:1111 Kernel driver in use: xhci_hcd 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: nazar-pc ~ lspci -d ::0c03 -k 00:14.0 USB controller: Intel Corporation Sunrise Point-H USB 3.0 xHCI Controller (rev 31) Subsystem: Gigabyte Technology Co., Ltd Sunrise Point-H USB 3.0 xHCI Controller Kernel driver in use: xhci_hcd nazar-pc ~ cat /proc/version_signature Ubuntu 4.9.0-10.11-lowlatency 4.9.0-rc8 --- ApportVersion: 2.20.3-0ubuntu8 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: nazar-pc 3227 F.... pulseaudio /dev/snd/controlC1: nazar-pc 3227 F.... pulseaudio CurrentDesktop: Custom DistroRelease: Ubuntu 17.04 EcryptfsInUse: Yes IwConfig: Error: [Errno 2] Немає такого файла або каталогу MachineType: Gigabyte Technology Co., Ltd.
