Have you checked the camera/USB connection in the device manager? Try deleting it there and allowing the driver to reinstall.

Did you take the lens cap off? :)

Have you tried the cameras with any other apps? like Skype, Chatroulet etc? There are a number of free webcam capture programs. See if one of those work. If they do it could be a problem with direct show and David.

What OS are you using? I'm on windows 10 and had buggy issues with usb2 cameras that i had to disconnect and reconnect it physically for david to unfreeze itself. This really screws up the camera pre-settings done before and has to be done all over again every time

... I have to "allow" camera use, when freshly plugged in and starting a camera software with Win7 and Win10 - could be, it's related to updated security settings?
