I tried it with the MX Master mouse and that also worked fine so long as the receiver was not plugged directly into the USB port. The mouse started working properly again. Upon disconnecting other USB devices I decided to use the USB extender for my WIFI Dongle with the Logitech Unifying receiver. Even with a different Logitech mouse, confirming it was the receiver and not the mouse. I had switched ports on both computers, avoided USB 3.0 ports, made sure no other USB devices were plugged in, yet the problem persisted. I plugged the Unifying receiver into a different computer and got the same erratic behavior in just a few minutes time. Windows 10 reported no problems with the device in Device Manager. the mouse was not tracking properly anymore.

I had a Logitech MX Master mouse with unifying receiver mated to a desktop USB port. Unfortunately I discovered this same solution by trial and error and many frustrating hours.
