For what its worth, I own and use a lot of Logitech Unifying Keyboards etc. They come pre linked out of the box. And SetPoint is only needed for the special functions. On my K350 keyboard its the special Blue keys. I almost never use Setpoint. I just download the Unifying software separately. I use M570 Trackballs instead of the Mice that came with the keyboards. I just unlink the keyboard from the mouse, then relink it to the Unifying dongle for my trackball. I don't know why your having this issue though? Unplug the other keyboard mouse and see what happens, you can always just plug them back in.
