Touchpad

The touchpad does not appear in /dev/input/by-id. The touchpad does not have ID_BUS, but more importantly it doesn't have bInterfaceNumber. The fact that the rule has the latter suggests that the rule will not work for non-USB devices (since bInterfaceNumber is a USB attribute). The following rules will add a by-id link:

FILE /etc/udev/rules.d/60-touchpad-events.rules

# determine class name for persistent symlinks
ENV{ID_INPUT_KEYBOARD}=="?*", ENV{.INPUT_CLASS}="kbd"
ENV{ID_INPUT_MOUSE}=="?*", ENV{.INPUT_CLASS}="mouse"
ENV{ID_INPUT_TOUCHPAD}=="?*", ENV{.INPUT_CLASS}="mouse"
ENV{ID_INPUT_TABLET}=="?*", ENV{.INPUT_CLASS}="mouse"
ENV{ID_INPUT_JOYSTICK}=="?*", ENV{.INPUT_CLASS}="joystick"

# set the bus ID
SUBSYSTEMS=="i2c", ENV{ID_BUS}=="", ENV{ID_BUS}="i2c"

# by-id links
KERNEL=="event*", ENV{ID_BUS}=="i2c", ENV{.INPUT_CLASS}=="?*", ATTRS{name}=="?*", SYMLINK+="input/by-id/$env{ID_BUS}-$attr{name}-event-$env{.INPUT_CLASS}"

Add grab="all" grabToggle="ctrl-ctrl" to the keyboard to capture all inputs on ctrl-ctrl.
