   3 # Pointingstick const-accel configuration, to make different brand / model
   4 # laptop pointingsticks have the same speed / feel, and per model adjustment
   5 # of the IBM TrackPoint driver's sensitivity setting
   6 #
   7 # The lookup keys are composed in:
   8 #   60-evdev.rules
   9 #
  10 # Note: The format of the "evdev:" prefix match key is a contract between the
  11 # rules file and the hardware data, it might change in later revisions to
  12 # support more or better matches, it is not necessarily a stable ABI.
  13 #
  14 # Supported hardware matches are:
  15 #  - Generic input devices match:
  16 #      evdev:input:bZZZZvYYYYpXXXXeWWWW-VVVV
  17 #    This matches on the kernel modalias of the input-device, mainly:
  18 #    ZZZZ is the bus-id (see /usr/include/linux/input.h BUS_*), YYYY, XXXX and
  19 #    WWW are the 4-digit hex uppercase vendor, product and version ID and VVVV
  20 #    is an arbitrary length input-modalias describing the device capabilities.
  21 #
  22 #  - Input driver device name and DMI data match:
  23 #      evdev:name:<input device name>:dmi:bvn*:bvr*:bd*:svn<vendor>:pn*
  24 #    <input device name> is the name device specified by the driver,
  25 #    <vendor> is the firmware-provided string from the kernel DMI modalias.
  26 #
  27 # To add local entries, create a new file
  28 #   /etc/udev/hwdb.d/71-pointingstick-local.hwdb
  29 # and add your rules there. To load the new rules execute (as root):
  30 #   udevadm hwdb --update
  31 #   udevadm trigger /dev/input/eventXX
  32 # where /dev/input/eventXX is the pointingstick in question. If in
  33 # doubt, simply use /dev/input/event* to reload all input rules.
  34 #
  35 # If your changes are generally applicable, open a bug report on
  36 #   http://bugs.freedesktop.org/enter_bug.cgi?product=systemd
  37 # and include your new rules, a description of the device, and the
  38 # output of
  39 #   udevadm info /dev/input/eventXX
  40 # (or /dev/input/event*).
