All of you have reported USB port instability issues that occur anywhere from once a week to couple of times a day.
Thunderbolt docks contain their own USB controller and power management firmware. Whereas most Intel-based motherboards use Intel's USB 3.x controller built into the PCH chipset, Thunderbolt docks use completely different ASMedia controllers.
- Do any of you already own a Thunderbolt 3 Dock with multiple USB ports?
- If so, have you tried moving your 'complex' USB devices to the Thunderbolt dock?
- Keyboard and mouse can most likely remain where they are. These are 'simple' USB devices.
Connecting 'complex' USB devices to a Thunderbolt 3 Dock might be useful in determining whether or not USB instability is due to something on the motherboard.
I don't have a TB3 dock, unfortunately. I also don't have any TB devices listed under the PCI page of SysInfo, despite all my BIOS settings being correct as per the guide, so I don't know if that would make a difference. Agree with @boob that it's not great to have a workaround, but with my current combination of different USB devices in different ports I've now been running for several hours without a glitch... So it would seem to point to either a power-consumption issue, or too-many-hubs-attached-to-each-other issue, or something similar.
