Program doesn't recognize my camera

Have hooked Canon camera up to Mac to import photos so I can begin stop animation. But when I’m asked on Capture page to dropdown Device tab and select camera, the camera isn’t listed. Computer obviously recognizes photos as they appear on iPhoto, but Toon Boom doesn’t. Should I have done something to photos for Toon Boom to recognized them? Or what is the problem?

I am using ToonBoom studio 6 with a Canon 60D. When i try to capture from the Canon, Toon Boom freezes. I also tried it with a Canon S2 IS. Same thing. Freeze. Force quit. It does work with the iSight camera. I am on a MacBookPro with 10.6.8.
