Go to VirtualBox settings of the VM and click on USB. There enable USB Controller then select USB 3.0 and add USB filter for your webcam as below.

There is a possibility that your webcam may not show there(I personally verified this issue on many other Linux distributions), then follow this tutorial and then try adding the USB filter for the webcam as mentioned above.
Now start your virtual machine and you can check the changes using lsusb
, there it will show the webcam properties exactly as you have on your host machine and no more "VirtualBox" prefix in the webcam label :D
