Webcam capture - timeout when requesting image

I'm using webcam capture to get a webcam image in Java via the following code:

Webcam webcam = Webcam.getWebcamByName("VF0415 Live! Cam Vid. IM Ultra 1"); // USB webcam
webcam.open();
BufferedImage image = webcam.getImage();
ImageIO.write(image, "JPG", new File("test.jpg"));


Unfortunately, I get a timeout with the following error:

[main] INFO com.github.sarxos.webcam.Webcam - WebcamDefaultDriver capture driver will be used
[atomic-processor-1] INFO com.github.sarxos.webcam.ds.cgt.WebcamOpenTask - Opening webcam VF0415 Live! Cam Vid. IM Ultra 1
[frames-refresher-[1]] ERROR com.github.sarxos.webcam.ds.buildin.WebcamDefaultDevice - Timeout when requesting image!

[frames-refresher-[1]] ERROR com.github.sarxos.webcam.ds.buildin.WebcamDefaultDevice - Timeout when requesting image!


I've looked through related issues on GitHub, and I've tried keeping my USB power on and intercepting the OS signals, but the error messages remain the same, giving me an essentially black image, as shown here:

Is there anything else I can try to fix this?
