What adapters show up in the hardware browser of imaqtool?
You can also use a webcam with the webcam hardware support package without having the Image Acquisition Toolbox at all. Do you want to try that instead?

See Walter's link below. In my experience, if I can talk to the webcam from the hardware support package, it will show up in imaqtool also, so I can talk to it in both ways.

Mallika,
webcam is not a part of the Image Acquisition Toolbox, and will not show up with IMAQTOOL.
If you want your webcam to show up with IMAQTOOL, install the OS Generic Support Package, and the webcam will show up under the winvideo adaptor.

I thought my webcam was showing up in imaqtool even before you had the webcam support package. Maybe not - that was a few years ago. Anyway my webcam shows up in imaqtool now, along with my regular machine vision camera.

The webcam will show up in IMAQTOOL if you have the OS Generic Support package(via the winvideo adaptor). And will also show up with webcamlist if its UVC Compliant.
OS Generic (winvideo) uses Windows Directshow drivers, and webcam uses Windows Media Foundation drivers.
