Change Key Mappings for a Specific Device

[eWheeler]

Hello,

The question: Can I change keymaps for a specific device? For example, can I change the keymap for a specific input device listed in "xinput --list" ?

Detail
I have a laptop keyboard and a USB 10-key pad for which I have remapped keys. Specifically, I have made the Keypad .0-9 work as numbers while numlock is off. This is important because numlock overrides the behavior of many of the laptop keys (if you have a laptop, press numlock and you'll see what I mean).

Currently I use xmodmap to remap the 10-key and it works quite well (Num_Lock is now BackSpace):


cat <<EOT | while read expr; do xmodmap -e "$expr"; done

keycode 77 = BackSpace
keycode 90 = KP_0
keycode 91 = KP_Decimal

keycode 87 = KP_1
keycode 88 = KP_2
keycode 89 = KP_3

keycode 83 = KP_4
keycode 84 = KP_5
keycode 85 = KP_6

keycode 79 = KP_7
keycode 80 = KP_8
keycode 81 = KP_9
EOTSo, is it possible to use xmodmap or some other tool to remap the keycodes or keysyms coming off a specific input device? This is my xinput --list:
