joy2key - make Logitech Cordless RumblePad 2 "hat" (a.k.a. d-pad) work in XBMC again

References to the source where I learned about this: [1] "Linux reports joystick hats as axes, because that's what the device reports them as."

XBMC 10.0 or probably a recent Arch update (SDL?) broke the joystick hat functionality for me. On XBMC startup, xbmc.log shows 0 hats and 6, instead of 4, axes:

17:00:36 T:3020363648 M:1703337984  NOTICE: Enabled Joystick: Logitech Logitech Cordless RumblePad 2
17:00:36 T:3020363648 M:1703337984  NOTICE: Details: Total Axis: 6 Total Hats: 0 Total Buttons: 12


My solution was to install joy2key from AUR. Here's my config:

#
# ~/.joy2keyrc
#

COMMON
-dev /dev/input/js0
-thresh -16383 16383 -16383 16383 -16383 16383 -16383 16383 -16383 16383 -16383 16383
#-autorepeat 5
#-deadzone 50

START xbmc
-X
# -axis <axis0min> <axis0max> <axis1min> <axis1max> ...
#       0 = left analog stick X-axis
#       1 = left analog stick Y-axis
#       2 = right analog stick X-axis
#       3 = right analog stick Y-axis
#       4 = hat (d-pad) X-axis
#       5 = hat (d-pad) Y-axis
#
# actions: Left/Right/Up/Down (arrow keys) - first letter capital!
#          plus/minus (ASCII characters) - lower case!
#          blank = special
# more info in /usr/include/X11/keysymdef.h
#
# .....0..........1.......2..........3..........4..........5......
#-axis Left Right Up Down minus plus plus minus Left Right Up Down
-axis blank blank blank blank blank blank blank blank Left Right Up Down

# EoF


joy2key needs to start after XBMC to be able to see its window. Here's my standalone XBMC box config:

#
# ~/.xinitrc
#

# Enable Ctrl+Alt+Bksp.
setxkbmap -option terminate:ctrl_alt_bksp &

# After a delay, start joy2key with XBMC config.
(sleep 5 && joy2key "XBMC Media Center" -config xbmc) &

# Start XBMC.
ck-launch-session xbmc-standalone --nolirc

# EoF

More info on how to install XBMC on Arch

And here is my joy2key config section for Boxee-source:

START boxee
-X
-axis blank blank Page_Up Page_Down blank blank plus minus Left Right Up Down
# .......1.2......3......4.5....6.....7...........8............9.0.1.2
-buttons v Return Escape c Left Right bracketleft bracketright i z s h


Part of .xinitrc which alternates between launching XBMC and Boxee:

(sleep 5 && joy2key "XBMC Media Center" -config xbmc) &
ck-launch-session xbmc-standalone --nolirc

(sleep 5 && joy2key "Boxee" -config boxee) &
ck-launch-session /opt/boxee/run-boxee-desktop


This gets respawned over and over from /etc/inittab:

x:5:respawn:/bin/su xbmc -l -c "/bin/bash --login -c /usr/bin/startx >/dev/null 2>&1"
