Tethering an Olympus to Aperture 3 not working

Looking at the Aperture 3 Manual regarding tethering it says :

"Note: For a list of cameras that Aperture supports for tethered shooting, go to http://www.apple.com/aperture/specs/raw.html. See your camera’s manual for information about setting up your camera for tethered shooting."

So I did and my Olympus E3 camera is listed

I followed the process to get the Tether HUD displayed and the HUD says no camera recognized

If I look in the "About this Mac" item at the USB connections it shows that the camera has been recognized.

Has any one got this to work? or for any camera.

Thanks for any info
