My eos90d has a nice mic attached to it. Will it work over USB or do I need to use the CamLink etc?
Your question is not exactly clear. I suggest that you record a video in the camera, and play it back to see if it records audio.
If you are asking about the Webcam Utility, then the instructions on its' use are quite clear. There is no audio. It is strictly a Web Camera. Audio is not supported.
