Solaar multiply detects my mouse, but forgets my keyboard.

[hillofbeans]

using :
Logitech Keyboard K375s
Logitech Mouse M325

and using the Logitech Unifying dongle that came with the mouse. ID 046d:c52b

Ubuntu Version: 16.04.4 LTS - Kernel 4.4.0-116-generic #140-Ubuntu SMP

everything up to date, as of 2018.Feb.25

It's identical output for the package solaar-gnome3

What I expected:
When I click on the solaar gui I expected it to report what it found. It reported three versions of my mouse, and three different unifying dongles, and no keyboard. After I typed on the keyboard, it changed to recognize the keyboard. But it still reported 3 dongles each with the same M325 mouse.
