Can't use my Web Cam on Virtual Machine of VirtualBox

First of all, I setup Debian x64 and am using Raspbian OS for my VM. I downloaded the expansion pack and I can see and select my camera from Devices tab. But I can't see my output in a webcam program such as Cheese. Also my webcam is visible in USB tab with port 0002 visible and my usb settings are enabled with USB 2.0. Moreover I tried to attach the camera from cmd, I got this error as a result:

D:>cd Oracle

Furthermore I tried to use the camera from USB tab in VM but I got this error:

Failed to attach the USB device Quanta Computer, Inc. [0002] to the virtual machine Swordian.

So, at last I still don't know what to do to use my webcam on my virtual machine after all those experiments. I'm looking forward to your help.
