A USB Reset is the controller forcibly removing itself from the USB bus.
This only happens if the controller detects a connection to the PC but is unable to communicate.
If the USB cable is physically removed from either controller or PC, the controller detects this and disables USB monitoring till the cable is reconnected.
As no resets are logged, this implies the controller has detected the connection is gone and is on standby. This means we need to look outside the controller for the cause of the physical connection dropout.
This could be hardware (cable, connectors, USB controller), software (Windows drivers, settings etc) or firmware (motherboard BIOS).
The controller does exercise the USB bus quite heavily with a thousand 2-way transmissions per second. Any latent issues with the USB subsystem will thus manifest first in devices that are heavy users.
Searching for "amd usb issues vr" brings up a few reports similar to yours.
