Are you on a Ryzen CPU? Apparently the USB ports that are connected to the CPU instead of the chipset can cause issues with input devices.

Google "ryzen usb bug". Here's a reddit thread about it. During high CPU load, the CPU-connected USB ports can become unreliable.

same on chipset (delta in mousetester 990-1010 (but stable))
