# 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*).
