        <pre>this is the commit for my Logitech K400
<a href="https://cgit.freedesktop.org/wayland/libinput/commit/?id=23614f75515ddb97089e2554a304aac3d951cff3">https://cgit.freedesktop.org/wayland/libinput/commit/?id=23614f75515ddb97089e2554a304aac3d951cff3</a>

i think you have to ad something like

...
(EVDEV_MODEL_MS_NANO_TRANSCEIVER|EVDEV_MODEL_LOGITECH_K400|EVDEV_MODEL_LOGITECH_K400_PLUS)
...
MODEL(LOGITECH_K400),
MODEL(LOGITECH_K400_PLUS),
...
EVDEV_MODEL_LOGITECH_K400 = (1 << 11),
EVDEV_MODEL_LOGITECH_K400_PLUS = (1 << 13),
...
# Logitech K400
libinput:mouse:input:b0003v046Dp4024*
 LIBINPUT_MODEL_LOGITECH_K400=1

# Logitech K400 +
libinput:mouse:input:...
 LIBINPUT_MODEL_LOGITECH_K400_PLUS=1
...

but Peter Hutterer knows it better.

i think at least you have to provide the ids of the Logitech K400+
(those in the header of evemu output)
# EVEMU 1.3
...
# Input device name: "Logitech K400"
# Input device ID: bus 0x03 vendor 0x46d product 0x4024 version 0x111
...</pre>
