Hi,
I assume you use the internal keyboard and not an external one?

Do you have the event devices installed? Please use the attached
program cev (compile with gcc -Wall -o cev cev.c). It will scan the
event devices and displays what it has found. Please check if there
is any keyboard in the list.

If anything is all right till this point please replace the attached include 
file 'debug.h' with that one in your pbbuttonsd source tree and compile
with --enable-debug. Start pbbuttonsd in a console (not as daemon) and watch 
the additional debug output. It shows the keycodes pbbuttonsd receives. Type 
a few keys and see if the keycode value changes.

Tell me your results

  Best Regards
     Matthias
