Logitech wireless keyboard k400r not working

21.06.2018 Admin
The problem is the only ones that still work are the volume control mute, up and down and the short-cut keys on the top left music, browser home, pc lock and pc restart. Click Finish to exit the Logitech Unifying Software. The only option which I find for Ubuntu was Solaar app.
I have not tested for full functionality. I can connect my Keyboard to my Android devices, keys and track pad working perfectly. Your keyboard should now be connected. Has anyone any ideas, as I am now getting desperate.

Hope you have fun creating the Welcome Page. Though it has some options, but do not include trackpad settings. I tried changing the batteries and nothing was spilled on it. Unable to customize my mouse or keyboard in SetPoi. It is smaller than a full size keyboard, with a large touch pad on the right side. The Biogas Vallee's brochure can be downloaded here.
