RCD covers only built-in Apple IR receivers and the Apple IR subsystem in OS X. It does not support or know of any other hardware.

To use an eHome/MCE receiver with Remote Buddy, you'll need to install the driver that accompanies it (Candelair) and run Remote Buddy to use it.

As of now, however, the product ID/vendor ID of your receiver is not part of the list of devices known to Remote Buddy, so you won't be able to use it.

If you have a little time for testing, I'll add the IDs of your hardware and send you a pre-release you can use to test with your hardware. Please let me know.

Best regards, 
Felix Schwarz
