What you have to have in mind first is that if you
i.e. use many usb input devices, there no way of telling
what index goes to which device: indexes depend on detection order.
Having said that, check /proc/bus/input/devices but that probably won't tell you more,
than hal already shows. |

well
hal is saying
| Code: | hal-device /org/freedesktop/Hal/devices/computer_logicaldev_input_0
udi = '/org/freedesktop/Hal/devices/computer_logicaldev_input_0'
info.subsystem = 'input' (string)
input.xkb.rules = 'base' (string)
linux.sysfs_path = '/sys/devices/LNXSYSTM:00/device:00/PNP0A08:00/device:19/device:1a/input/input5/event5' (string)
info.category = 'input' (string)
info.product = 'Video Bus' (string)
input.xkb.model = 'evdev' (string)
info.parent = '/org/freedesktop/Hal/devices/computer' (string)
info.capabilities = { 'input', 'input.keys', 'button' } (string list)
info.udi = '/org/freedesktop/Hal/devices/computer_logicaldev_input_0' (string)
input.xkb.layout = 'us' (string)
input.xkb.variant = '' (string)
input.device = '/dev/input/event5' (string)
linux.hotplug_type = 2 (0x2) (int)
input.x11_driver = 'evdev' (string)
input.product = 'Video Bus' (string)
linux.subsystem = 'input' (string)
linux.device_file = '/dev/input/event5' (string)
info.addons.singleton = { 'hald-addon-input' } (string list) |
and I am asking, which device is it in my laptop?
okay, I did unplug USB mouse and keyboard, still there  |

This will give you all of them:
| Code: | #!/bin/bash
for arg in `hal-find-by-capability --capability input`; do
hal-device $arg;
done |
Keyboards will have input.keys, buttons have input.button, switches have input.switch etc. |

I did use a TRICK
| Code: | | cat /dev/input/event5 |
and pressing FN+F5 or FN+F6 {brightness control} I did noise characters
so I know what is event5 now ... |
