# Keymaps table
#
# This table creates an association between a keycode file and a kernel
# driver. It can be used to automatically override a keycode definition.
#
# Although not yet tested, it is mented to be added at udev.
#
# To use, you just need to run:
# ./ir-keytable -a
#
# Or, if the remote is not the first device:
# ./ir-keytable -a -s rc1 # for RC at rc1
#
# Format:
# driver - name of the driver provided via uevent - use * for any driver
# table - RC keymap table, provided via uevent - use * for any table
# file - file name. If directory is not specified, it will default to
# /etc/rc_keymaps.
# For example:
# driver table file
# cx8800 * ./keycodes/rc5_hauppauge_new
# * rc-avermedia-m135a-rm-jx ./keycodes/kworld_315u
# saa7134 rc-avermedia-m135a-rm-jx ./keycodes/keycodes/nec_terratec_cinergy_xs
# em28xx * ./keycodes/kworld_315u
# * * ./keycodes/rc5_hauppauge_new
# Table to automatically load the rc maps for the bundled IR's provided with the
# devices supported by the linux kernel
#driver table file
