The ITE keyboard controller firmware (version 0xAB83) is shared between the Clevo PA70ES and the X+ piccolo series. The piccolo's hwdb rule matches by input device ID (evdev:input:b0011v0001p0001eAB83*) and remaps scan code 0x9c (KP_Enter) to Enter, since the piccolo has no numpad and its main Enter key sends the wrong scan code. The Clevo PA70ES has a real numpad. The piccolo rule matches it because both laptops use the same ITE controller firmware, which breaks KP_Enter on the PA70ES. Add a DMI-specific override that restores KEY_KPENTER for 0x9c on the PA70ES. The piccolo rule should ideally be narrowed to use DMI matching instead of input device ID to avoid catching other laptops with the same ITE controller firmware.
Files in this directory specify a description of hardware devices, in the form of mappings from modalias-like keys (which identify specific hardware devices) to udev properties. Files in this directory are not read by udev directly. Instead, man:systemd-hwdb(8) compiles them into a binary database. See man:hwdb(7) for an overview of the configuration file format, and man:systemd-udevd.service(8) for a description of the udev daemon. Use 'systemd-analyze cat-config udev/hwdb.d' to display the effective config.
