logiSwitch

Note

This repository contains scripts to allow switch 2 logitech devices from one computer to another. Both devices and computers must use the logitech unifying dongle. Connectiong via bluetooth did not work through my tests.

It is heavily based on this repository : https://github.com/marcelhoffs/input-switcher

It also use hidapitester to send the command. It is provided in the repo, but you can get latests version here : https://github.com/todbot/hidapitester/releases

The purpose is to assign, on both OS, the script to a key / mouse button, so that chen it will be used, both devices switch to the other computer.

In my case, I switch from one windows computer (Windows 10) to a Mac, and vice versa.

As a sample, the script is binded to the MX Master 3 small button on the side :

Windows

Windows configuration consists in 2 components :

a batch script that "does" the switch
hidapitester binary for windows

Both files must be put in the same location, whereever you want.

Mac

Mac configuration consists in 3 components :

a bash script that "does" the switch
an apple script that will encapsulate the script into an app, so that you can assign it in logitech options / options+ .It is not provided since you will have to create your own.
hidapitester binary for macOS

Everything is supposed to be copied in /Applications/logiSwitch/ .

You might have to make the script executable :

chmod +x logiSwitch.sh

To create the applescript, simply :

open applescripteditor, and create a new script
paste the following command (adapt to where you stored the files) :

do shell script "bash /Applications/logiSwitch/logiSwitch.sh"

Adapting the scripts

You will have to adapt the scripts depending on your setup.

Mainly, you have to identify 2 things (on each computer) for each device :

channel corresponding to the device you want to go to from current computer - MSE_CH / KYB_CH - 0x00 for channel 1, 0x01 for channel 2, 0x02 for channel 3
id of the device - MSE_ID / KYB_ID - it depends on the order you set up your device to the unifying receiver : 0x01 for the first device , 0x02 for the second device , adn so on . The order seems to be reflected in LogiOptions / logiOptions +

Last thing, the scripts provided suppose that you have the following devices :

an MX keyboard (C value = 0x09)
an MX Master 3 mouse (C value = 0x0a)

If you have other device, you will have to change "C" value also in the scripts. If you have other devices, you have to figure out their value.

On the Mac script, you also have to adapt path to hidapitester if you did not use the same as mine.
