The VirtualBox Version & Extension can be downloaded from the same place at https://www.virtualbox.org/wiki/Downloads

The Extension shows as VirtualBox 4.3.16 Oracle VM VirtualBox Extension Pack where 4.3.16 is simply the latest version.

There are 2 ways to install it, you either Open VirtualBox and it will tell you that it is missing the Extension, followed by an option to download it. Another is downloading the Extension from the link provided, opening VirtualBox, going to the main menu and selecting File - Preferences. You can also press after opening VirtualBox CTRL+G.

From there go to Extension and simply click on the Add button, find the downloaded extension file which corresponds to the VirtualBox version you are using and add it.

Note that BEFORE adding the extension I recommend adding your user to the vboxusers group which is created after installing VirtualBox.

sudo usermod -aG vboxusers USERNAME

Adding yourself to the vboxusers in combination with the VirtualBox Extension will give you full USB support.

  • problem is according to the vituralbox that is installed it is version 4.3.10 and there id no extension with this ver # and when i tried to use the extension for ver 4.3.16 it gave me an error Sep 14, 2014 at 20:10
  • You can then upgrade the current one you have to the latest by simply downloading the latest virtualbox. Then folllow up with the correct installation. Remember that you can NOT use an extension with any other virtualbox version than the one it mentions. The 4.3.16 will only work with the same one. Sep 14, 2014 at 20:29
  • @CharlesHockenberry and Luis: Old extension packs for 4.3.x are here: virtualbox.org/wiki/Download_Old_Builds_4_3
