Linux virtualbox connect usb

@learner That’s very strange, since -aG and -a -G should have the same effect when passed as options to usermod . Is it possible that instead you had not logged out and back in the first time, but had done so the second time?

@EliahKagan its been so many months so I have forgotten. But your explanation is the logical one so may be I have logged out and back the second time.

sudo apt-get install gnome-system-tools 

I had a host ubuntu and a guest ubuntu. Most importantly do this on host not guest and one also needs Virtualbox extension pack apart from the guest additions (and save yourself an hour and a frustration).

The vboxusers will be in the /etc/group file. You edit it with something like nano .

Add your user to the vboxusers line, or create one if necessary.

As Takkat has pointed out, to get full USB device support, you’ll need to install the full version of Virtualbox (not the OSE).

The ppa I have for the «official» virtualbox is here:

/etc/apt/sources.list.d/virtualbox-offical-source.list: deb http://download.virtualbox.org/virtualbox/debian maverick contrib #VirtualBox Offical Source 

In Ubuntu 16.04 LTS, after the initial install with

sudo apt install virtualbox virtualbox-guest-additions-iso 

sudo usermod -a -G vboxusers $USER sudo apt install virtualbox-ext-pack 

Then I could enable USB 2/3 support in the machine settings.

What the virtualbox-ext-pack actually does, is download the required files from http://download.virtualbox.org/virtualbox and prompt you to accept the license before installing.

I had the same problem. After trying all the other solutions I realised my problem.

I had downloaded virtualbox from the Ubuntu Software Center, which didn’t have the latest version of virtualbox, so I had accidently downloaded the wrong version of «Oracle VM VirtualBox Extension Pack».

1. open virtualbox, click help, click about, find your virtualbox version number.
2. Goto https://www.virtualbox.org/wiki/Download_Old_Builds_4_3 (replace «4_3» with your version).
3. Download the «Extension Pack» that matches your virtualbox version.
4. Install that, and it might ask you if you would like to downgrade, click yes.

I had the same problem and fixed it by clicking in the VirtualBox group of my user. You can access it installing gnome-system-tools (it does not come with Ubuntu 12.04 Precise Pangolin), either via the Ubuntu Software Center, Synaptic or by typing in the terminal:

sudo apt-get install gnome-system-tools 

Remember that to paste in the terminal you have to use Ctrl + Shift + V , as opposed to Ctrl + V .

You will probably have to enter your password to allow the installation and add a Y (as in yes) to finish installing the packages.

Then you head to your Dash home and type users. You will see two applications. The good one is Users and Groups.

You then have to click on Advanced settings for your user and enter your password.

Now you will be shown a window with three tabs. Click on User Privileges. Find the line that says Use Virtualbox virtualization solution and then OK.

You may be asked to enter your password again. Then click on Close and log-out and log-in again.

When you start VirtualBox, you should see a whole bunch of new USB devices.

How to Access USB from VirtualBox Guest OS

There are times when you need to access USB from VirtualBox. For instance, you installed Kali Linux in VirtualBox and a USB wireless network adapter is required to do penetration testing. This simple tutorial will show you how to easily access your USB thumb drive, USB hard disk, or USB wireless network adapter in your Virtualbox guest OS.

It’s assumed that you have already set up VirtualBox on your host OS.

Step 1: Install Virtualbox Extension Pack

VirtualBox by default only supports USB 1.x devices. VirtualBox extension pack includes support for USB 2.0 and USB 3.0 devices, VirtualBox RDP and PXE boot for Intel cards. You must install the extension pack with the same version as your installed version of VirtualBox.

To check the version of your VirtualBox, open VirtualBox manager, then go to Help > About VirtualBox . Once you know the version number, go to http://download.virtualbox.org/virtualbox/ in your web browser to download VirtualBox extension pack which ends with .vbox-extpack extension.

Once downloaded, in VirtualBox manager go to File > Preferences > Extensions. Click the add button to add VirtualBox extensions pack from your hard disk.

Once you choose the extension pack, click Install button to install it. You can see what functionalities it adds to your virtual machine in the description.

Then click Agree to accept VirtualBox license.

So now Virtualbox USB support is enhanced.

Step 2: Add Your User to vboxusers Group

In order for VirtualBox to see your USB devices, your user must be in the vboxusers group. Open up a terminal window (Ctrl+Alt+T), then run the following command. Replace your-username with your real username. (I assume your host OS is a Linux distro such as Ubuntu, instead of Windows).

sudo gpasswd -a your-username vboxusers

Now log out and log back in so the changes can take effect. To check which groups your user account belongs to, run:

If you still aren’t in the vboxuser group, then restart your computer.

Step 3: Enable USB Controller and Add New USB filter

Click settings for your virtual machine.

Select USB on the left pane. Then choose USB 2.0 controller or USB 3.0 controller. Note that you can only enable one type of controller. Next, insert your USB device to your host machine and click the add button to add new USB filter.

Choose your USB device and Click OK.

Step 4: Access USB from VirtualBox

Now boot up your virtual machine and you will see your USB device in the guest OS. It should be noted that your host OS won’t be able to see the USB device while it’s being used by VirtualBox.

To unmount USB device from guest OS, select devices > USB and uncheck your USB device.

To mount USB in VirtualBox again, simply select your USB drive in the list.

How to Boot VM From USB Stick

Let’s say you created a bootable USB stick and you want to boot your VirtualBox VM from the USB stick. Virtualbox allows your VM to access raw hard disk, by creating a special VMDK image. I assume your host OS is Linux.

First, find the device name of your USB stick.

Mine is /dev/sdb . Then run the following command to create a VMDK image file /tmp/usb.vmdk .

sudo VBoxManage internalcommands createrawvmdk -filename /tmp/usb.vmdk -rawdisk /dev/sdb

Change the ownership of this file. Replace username with your real username.

sudo chown username:vboxusers /tmp/usb.vmdk -R

Then add your user account to the disk group, so you can access raw hard disk.

sudo adduser username disk

Log out and log back in for the changes to take effect. Then open Virtualbox and attach the raw disk ( /tmp/usb.vmdk ) to your VM.

How to Enable USB in VirtualBox

If your data center depends on VirtualBox and your virtual machines depend on the USB device, you’ve perhaps noticed that USB doesn’t support by default unless you’ve manually enabled it.

In this article, we will explain to you how to enable USB support on Virtualbox. The current version of VirtualBox 6.0 comes with support for USB 3.0, and to take advantage of it, you need to install the latest version of VirtualBox Extension Pack.

This tutorial presumes that you already installed VirtualBox on your Linux and VirtualBox guest additions on your virtual machines. If you haven’t, you can install it using the following articles.

How to Install the VirtualBox Extension Pack

To install the latest version of Extension Pack, head over to the Virtualbox Downloads page and grab the file for All supported platforms.

1. Once you’ve downloaded, open up VirtualBox –> Click File –> Preferences in the Menu.

2. Next, click on the Extension tab and then click the + sign.

3. Select the downloaded Extension Pack and install it as shown.

4. Scroll through the Virtualbox License and then click I Agree button to install it.

5. Enter your sudo password and allow the installation to finish.

Enabling USB Access to User

To allow a user to access the USB subsystem, you need to add the user (running VirtualBox) to the vboxusers group using the following command.

$ sudo usermod -aG vboxusers

Where USERNAME is the name of the user running the VirtualBox.

Once the command runs successfully, logout and log back into the system.

Enabling USB Support in VirtualBox

Start up VirtualBox, right-click on the virtual machine that needs access to a USB device, and click Settings.

In the virtual machine’s Setting tab, click on USB to see the available USB devices. Click on the + sign to add a new device.

Once USB device added, start up the virtual machine to have access to the data on the USB device. If you want to enable more USB devices, go back into the Settings –> USB and add the devices.
