I don't think recompiling is necessary- this sounds like a keymap issue (not as in "proper" keymaps, but as in how irk maps infrared signals to key presses)--you'll notice that if you select Belkin or Pocketop, some key presses show up, but as the wrong letter. This means IRK itself is working, but it is translating the keypresses wrong. I think if you were to put the Targus settings file (I don't remember which it is offhand), that it would work for you. I'll look at the settings in my Z (I'm back to the Sharp ROM right now) if I have a chance today and post the settings.
