+# This file is part of systemd.
+#
+# Database for the DPI setting of mice, trackballs, other pointer devices that
+# cannot be queried directly.
+#
+# The lookup keys are composed in:
+# 70-mouse.rules
+#
+# Note: The format of the "mouse:" 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 format:
+# mouse:<subsystem>:v<vid>p<pid>:name:<name>:
+#
+# Supported subsystems: usb, bluetooth
+# vid/pid as 4-digit hex lowercase vendor/product
+#
+# if vid/pid is unavailable, use
+# mouse:*:name:<name>:
+# if name is unavailable, use
+# mouse:<subsystem>:v<vid>p<pid>:*
+#
+# For example, the following 5 matches all match the same mouse:
+# mouse:usb:v17efp6019:name:Lenovo Optical USB Mouse:
+# mouse:usb:*:name:Lenovo Optical USB Mouse:
+# mouse:usb:v17efp6019:*
+# mouse:*:name:Lenovo Optical USB Mouse:
+#
+# DPI settings are specified as
+# MOUSE_DPI=<dpi>[@<frequency>]
+#
+# Where <dpi> is the resolution in dots per inch, and <frequency> the
+# optional sampling frequency in Hz.
+#
+# The value of MOUSE_DPI is:
+# - a single integer for single-resolution mice, e.g.
+# MOUSE_DPI=800
+# or, if the frequency is known:
+# MOUSE_DPI=800@120
+# - a space-separated list of resolutions for multi-resolution mice.
+# The default resolution must be prefixed by an asterisk, the resultions
+# in the database must be as shipped by the manufacturer. e.g.
+# MOUSE_DPI=400 *800 2000
+#
+# The order of resolutions is as configured by the HW manufacturer or in
+# ascending order, whichever appropriate.
+#
+# The frequency must be given to either none or all resolutions. If the
+# device supports multiple frequencies, the order of items is
+# MOUSE_DPI=r1@f1 r2@f1 r3@f1 r1@f2 r2@f2 r3@f2
+#
+# If the default manufacturer-set resolution is unclear, a resolution of
+# 800 or 1000 should be set as default, if available. If neither is
+# available, choose the "middle" resolution value of those available.
+#
+# The list may contain a single item which must be marked with an
+# asterisk.
+#
+# Local changes to the a non-default resolution of the mouse (e.g. through
+# third-party software) must not be entered into this file, use a local
+# hwdb instead.
+#
+# To add local entries, create a new file
+# /etc/udev/hwdb.d/71-mouse-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 mouse 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*).
