USB Webcams are Not Working in Windows Guest (w. Extension Pack & Guest Additions)

[ppan]

I am trying to get my webcam, Microsoft LifeCam (USB), to work in a Windows 7 (64 bit) Guest on Windows 7 (64 bit) Host.

The camera works fine in the Host using two different applications:

1. Microsoft LifeCam software
2. Portable Webcam (​http://sourceforge.net/p/portablewebcam)

I am currently using VirtualBox 5.2.8 w. Guest Edition and Extension Pack. I select the WebCam under devices (and not in USB devices). The camera is recognized in Device manager. However, the Camera is not working;

1. Microsoft LifeCam software: "No Camera found"
2. Portable Webcam: Camera light turns on then off. I just get a white screen

I can use the camera in the Host, using either application, even when virtual box is running with the camera attached to the Guest (Should that work? I had expected the Guest to take ownership of the camera).

I also tried Logitech C270 Webcam and I have the same problem.

Please help, I have spent several months on this using different guests and versions of VirtualBox. Thank you in advance!

p.s.

1. The cameras works fine in VMware virtual machines and Windows 7 Host/Guests.
2. I posted this previously in the forum but got no response (​https://forums.virtualbox.org/viewtopic.php?f=6&t=87569)

Hmm... I must have missed your post in the forums, sorry about that. Do you mind if we continue this discussion in the forums for the benefit of the masses? And if there's a need we resume here with the conclusions.

Did you have a chance to look at my response in the Forum (Posted on June 4th)?

I did. But if you recall I had to send my "grandpa" PC for a brain transplant. (Re)Installing Win10x64 again because it kind of... died in the process. Will reply in the thread.

Synopsis: it works.
