Missing commands

I noticed that the IRUSB driver doesn't have the Play/Pause command, nor the Guide command.  Can these be added?  Or is there a "test" command for the IRUSB driver, I coudln't seem to find one.  It would be nice to have since there are hundreds of potential commands out there that might be useful.

In case anyone else comes across this thread later I fiunally figured out how to send any IRUSB command. You just need to do AV|xx~Remote~<IRUSB_CMD>. You'll have to search the IRUSB command API to find the right code but this allows you to send any command you want.
