Reconfigures the way the function keys on Logitech K290 keyboards works. This is a python port of https://github.com/milgner/k290-fnkeyctl

Requires python-libusb1, to install sudo pip3 install libusb1

or sudo apt install python3-libusb1

Works with python 2 and python 3

Tested on Ubuntu 15.04, 16.04, 17.04 and 18.04

Opening the device with libusb requires advanced permissions, so run it with

    sudo python3 k290_fnkeyctl.py
or
    sudo ./k290_fnkeyctl.py

Afterwards, you'll have regular function key behaviour. If you want to switch back, just append -r or --reset.

To automatically run the program when the device is plugged in, you can use the included udev rules script as a template. Or just automatically install them along with the executable with

sudo ./install.sh

Which will copy the executable to /usr/local/sbin and install the udev rules into /etc/udev/rules.d. Now you'll just need to tell udev to apply the new rules:

sudo udevadm control --reload-rules
sudo udevadm trigger --subsystem-match=input
