For example:

mice=`hal-find-by-capability --capability input.mouse`
for m in $mice; do
    mice_dev="$mice_dev `hal-get-property --udi $m --key input.device`"
done
keyboards=`hal-find-by-capability --capability input.keyboard`
for k in $keyboards; do
    keyboard_dev="$keyboard_dev `hal-get-property --udi $m --key input.device`"
done

Of course, if your program is in C or Python, you can do things much
more powerfully.
