# This file is part of systemd.

#

# The lookup keys are composed in:

# 60-evdev.rules

#

# Note: The format of the "evdev:" prefix match key is a

# contract between the rules file and the hardware data, it might

# change in later revisions to support more or better matches, it

# is not necessarily expected to be a stable ABI.

#

# Match string formats:

# evdev:<modalias>

# evdev:name:<device name>:dmi:<dmi string>

#

# To add local entries, create a new file

# /etc/udev/hwdb.d/61-evdev-local.hwdb

# and add your rules there. To load the new rules execute (as root):

# udevadm hwdb --update

# udevadm trigger /dev/input/eventXX

# where /dev/input/eventXX is the device in question. If in

# doubt, simply use /dev/input/event* to reload all input rules.

#

# If your changes are generally applicable, open a bug report on

# http://bugs.freedesktop.org/enter_bug.cgi?product=systemd

# and include your new rules, a description of the device, and the

# output of

# udevadm info /dev/input/eventXX

# (or /dev/input/event*).

#

# Allowed properties are:

# EVDEV_ABS_<axis>=<min>:<max>:<res>:<fuzz>:<flat>

#

# where <axis> is the hexadecimal EV_ABS code as listed in linux/input.h

# and min, max, res, fuzz, flat are the decimal values to the respective

# fields of the struct input_absinfo as listed in linux/input.h.

# If a field is missing the field will be left as-is. Not all fields need to

# be present. e.g. ::45 sets the resolution to 45 units/mm.
