+#
+# Pointingstick const-accel configuration, to make different brand / model
+# laptop pointingsticks have the same speed / feel, and per model adjustment
+# of the IBM TrackPoint driver's sensitivity setting
+#
+# 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 a stable ABI.
+#
+# Supported hardware matches are:
+# - Generic input devices match:
+# evdev:input:bZZZZvYYYYpXXXXeWWWW-VVVV
+# This matches on the kernel modalias of the input-device, mainly:
+# ZZZZ is the bus-id (see /usr/include/linux/input.h BUS_*), YYYY, XXXX and
+# WWW are the 4-digit hex uppercase vendor, product and version ID and VVVV
+# is an arbitrary length input-modalias describing the device capabilities.
+#
+# - Input driver device name and DMI data match:
+# evdev:name:<input device name>:dmi:bvn*:bvr*:bd*:svn<vendor>:pn*
+# <input device name> is the name device specified by the driver,
+# <vendor> is the firmware-provided string from the kernel DMI modalias.
+#
+# To add local entries, create a new file
+# /etc/udev/hwdb.d/71-pointingstick-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 pointingstick in question. If in
+# doubt, simply use /dev/input/event* to reload all input rules.
+#
+# If your changes are generally applicable, preferably send them as a pull
+# request to
+# https://github.com/systemd/systemd
+# or create a bug report on https://github.com/systemd/systemd/issues and
+# include your new rules, a description of the device, and the output of
+# udevadm info /dev/input/eventXX.
+#
+# Allowed properties are:
+# POINTINGSTICK_CONST_ACCEL
+# POINTINGSTICK_SENSITIVITY
+#
+# Entries should be sorted with growing _SENSITIVITY and _CONST_ACCEL.
+#
+#########################################
+# POINTINGSTICK_CONST_ACCEL #
+#########################################
+#
+# Trackpoint const accel settings are specified as
+# POINTINGSTICK_CONST_ACCEL=<accel>
+#
+# Where <accel> is a floating point number, using a '.' seperator, specifying
+# by how much to multiply deltas generated by the pointingstick to get
+# normalized deltas.

+#########################################
+# POINTINGSTICK_SENSITIVITY #
+#########################################
+#
+# TPPS/2 IBM TrackPoint driver sensitivity sysfs setting
+# POINTINGSTICK_SENSITIVITY=<sensitivity>
+#
+# Where <sensitivity> is a number between 0 and 255, note this property
+# only applies to TPPS/2 IBM TrackPoint devices, see
+# drivers/input/mouse/trackpoint.c in the Linux kernel sources.
