What is the Log and Capture preset for a Canon XH A1s

I am trying to Log and Capture with my Canon XH A1s. I keep getting an error message saying: Unable to Initialize Capture Device. Device is not corrected or the capture preset is not setup correctly. You my still log offline clips. This might also happen if you play DV footage in an HDV device.

Also, when I plug in the firewire cable to my iMac, I tested it out with iMovie, but after a shoot iMovie did not recognize the camera anymore. So could someone please help. Thanks.🙂
