What is the "USB Controls" device listed in “Settings ˘ Bluetooth & other devices?”

Solution 1:

I found out that the "USB Controls" audio device corresponds to the Fresco Logic FL1100 USB 3.0 eXtensible Host Controller, which is a component inside of my LG UltraFine 5K external monitor.

Whenever I detach the monitor by disconnecting the USB-C cable from the monitor or from my Intel Thunderbolt 3 port, the USB Controls disappear. And when I reconnect the cable, the USB Controls entry shows up again.

The Fresco Logic USB 3.0 eXtensible Host Controller is listed in the Windows Device Manager under the "Universal Serial Bus controllers" node. When I disable it, the USB Controls disappear and when I re-enable it, the USB Controls re-appear.

Finally, while there are many hardware devices listed in “Control Panel > Devices and Printers > Devices,” on the hardware tab of the USB Controls device properties dialog window, these are all device sub-nodes present under the Fresno Logic FL1000 controller node.
