How can I use my webcam with Ubuntu running in VirtualBox?

This is possible, but requires a few steps to get working properly:

  1. Make sure the virtual machine is not running and your webcam is not being used.
  2. Bring up the main VBox window and in the details tab for your Win7 machine click USB.
  3. Make sure "Enable USB Controller" is selected. Also make sure that "Enable USB 2.0 (EHCI) Controller" is selected too.
  4. Click the "Add filter from device" button (the cable with the '+' icon).
  5. Select your device from the list.
  6. Now click OK and start your VM.

This will cause the device to show up as if it were plugged into the VM. From there, you should be able to use it or install drivers if necessary.


The same answer of @Nathan Osman , However , it required to belong to vboxusers group to be able to see all devices on adding one.

sudo usermod -a -G vboxusers $(whoami)

Logout & login again , check if your vboxusers displays in this command :

groups

Many built-in cameras will not appear as USB devices.

In this case you need to install the VirtualBox Extension Pack and possibly the Guest Additions (not sure about it).

Then restart the VM and in the top menu Devices there should be a new submenu Webcams. Enable your webcam from there and it should become available in the VM.
