Does not operate with only one device attached

I have a scenario where I am using the usb 3.0 switch to manage a laptop and a desktop at home. The desktop is always connected but I will often disconnect the laptop to use elsewhere. When that is done, the switch (sometimes immediately, sometimes after a few minutes) begins flashing. The switch does not respond to button presses if I attempt to switch to the computer that is still connected.

That said, must there always be two computers connected for the switch to work?
