# driver, <vendor> is the firmware-provided string exported

# Scan codes are specified as:
# KEYBOARD_KEY_<hex scan code>=<key code identifier>
# The scan code should be expressed in hex lowercase and in
# full bytes, a multiple of 2 digits. The key codes are retrieved
# and normalized from the kernel input API header.

# A '!' as the first charcter of the key identifier string
# will add the scan code to the AT keyboard's list of scan codes
# where the driver will synthesize a release event and not expect
# it to be generated by the hardware.

# To debug key presses and access scan code mapping data of
# an input device use the commonly available tool: evtest(1).
#
# To update this file, create a new file
# /etc/udev/hwdb.d/70-keyboad.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 keyboard 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*).
