How can I get my windows phone to be detected on my mac?

I have a windows phone 7 HTC-HD7 that was able to be read by my mac until last jus recently. I got a new update for the windows phone 7 connector software today, but didn't help.|||Because the software programs are not of the same author, the mac won't pick up the phone. I had the same problem with a digital camera, and had the same result. My camera detected a mac, but the mac did not detect the camera.
