It doesn't look like this? Settings/System/Debugging (wiki)?

No. Raspbmc adds:

Code:

<loglevel hide="true">0</loglevel>

to advancedsettings.xml which stops that option showing up.

However I believe the CEC comes out in log whatever debug settings you have, so:

Code:

tail .xbmc/temp/xbmc.log

after pressing a key should indicate if CEC saw it, and what the key was.
