Can you test this device on a modern linux kernel version? The one used by amlogic is many years old. If it still doesn't work please report back to LibreELEC and we can possibly quirk the device handling in our udev scripts.

I've googled for a way to tell libinput to ignore my gamepad again and this time I came across LIBINPUT_IGNORE_DEVICE flag. How could I have missed it when I searched for something like that for the first time? I could have saved myself a lot of time!

I've added a new udev rules like this:
SUBSYSTEM=="input", ATTRS{name}=="Gamepad", KERNEL=="event*", MODE="0666", ENV{LIBINPUT_IGNORE_DEVICE}="1"
SUBSYSTEM=="input", ATTRS{name}=="Gamepad", KERNEL=="event*", MODE="0666", ENV{ID_INPUT_JOYSTICK}="1"

The first rule stops Kodi from blocking the events and makes the gamepad work again with the Linux driver (joydev).
The second rule makes it work even with the Udev driver (evdev).
