I was following this question but found a problem.
Use my webcam with Ubuntu running in VirtualBox
I used guvcview to test the camera, it works. I installed the 12.04 virtualbox release from their website and installed the extension pack. But when I click the usb with the green plus sign it says no devices available.
First install dkms :
sudo apt-get install dkmsNext install Gnome-System-Tools
sudo apt-get install gnome-system-toolsNow launch the application - Users and Groups. If you're using unity you can do this by tapping the Super key and type user then click Users and Groups icon to start up the User Settings.
Click Manage Groups, find vboxusers, click properties, add your own user name and any other desired users to the vboxusers group. Click Ok. Alternative to using this GUI tool to add user to the group is to use the command sudo usermod -a -G vboxusers $USER .
It will also prove to ensure guest additions and extension pack are installed. On command line use: sudo apt-get install virtualbox-guest-additions-iso and sudo apt-get install virtualbox-ext-pack .
Next you'll have to log out (sudo restart lightdm if you're using this DM) and back in. Now start VirtualBox and proceed with adding the USB devices.
