Thanks evilavatar, but I do have the manual. What I don't have is knowledge about building. To clarify, I should connect the IR receiver to the CIR1, not usb? Any guidance on where to look for an adaptor (keywords to search for?)
FYI, The CIR1 has 5 pins (6 pin layout, with one missing), the IR Receiver cable has 10 pins. See image from manual below.
Here's a link to the biostar 880G manual... it'll open in pdf format and though it looks like form the diagrams that you will need some type of cord extension to correct for the differing plugs. Any specs on the IR input device you have?
