**Describe the bug**
After pairing the K375s logitech keyboard the white 3 white numeric keys that allow me to switch between devices, no longer work. This then means to use the keyboard on my other 2 devices I have to unpair from Ubuntu20 machine first, then repair it multiple times on my other machines(as you can no longer assign the desired device key number on first re-pair as its always defaults to key 1 until paired once on other machines). 

**To Reproduce**
Steps to reproduce the behaviour:
1. Pair the devices to other machines.  I'm using a Mac (logitech unify software and drivers) and an older Ubuntu18 with Solaar 0.9.2 as my 2 other devices) 
2. Then pair K375s keyboard to the solaar 1.0.1 on Ubuntu 20 (my 3rd device). 
3. The white device assignment keys will no longer function and you can not switch between devices. Beep sounds on Ubuntu20 machine.

pfps commented 3 years ago

Solaar version 1.0.1 does not have any understanding of the MULTIPLATFORM feature of the device, which I believe is what these keys use. So I don't know that Solaar could be doing to interfere with the switching.

Except, did you try pressing these keys both with and without the Fn key pressed? The device-switching keys are Fn keys so maybe their default behaviour is changed by Logitech software.

pfps commented 3 years ago

Also, newer versions of Solaar have features relevant to this device.

ghost commented 3 years ago

Thanks pfps, it seems the behaviour is different in 1.0.1. I just tried it with pressing the FN key plus F1 and F2 etc/. In the old Solaar 0.9.3 F1-F3 just let the keyboard switch between devices without the FN key. I can work with that. Thank you.
