So using evtest and xinput, I've been able to verify that all the keys are making it to my n900 and confirmed that the default keycode mappings should be valid. However, for some reason, the mappings aren't working. Only the following keys are working:
- all letters
- space
- tab
- backsapce
- enter
- comma
- period
- shift (though not at the same time as i press another key)
- esc
- directional keys
- f keys

Numbers, most special characters, and most special keys (such as capslock, ctrl, alt, etc) aren't working though events are sent in. Any idea what could be wrong? I've tried different mappings, but I can't get any of these other keys to work. Has anyone else experienced similar issues and/or know how to get numeric keys and special keys working?
