How to set up USB for Virtualbox?

I'm using Ubuntu Maverick and Virtual Box 3+. I have Windows 7 Ultimate. The problem is that it doesn't detect USB drives in Windows 7, but USB peripherals (mouse + keybord) are working.

I followed these instructions, but I can't find the user group vboxusers. How can I continue? I would also like to upgrade to the latest version without any risk (without losing my virtual hard disk drive).

1. Install Extension Pack

USB 1.0 is supported in the version installed from the Ubuntu repositories (from VirtualBox > 4.x).

For USB 2.0 and USB 3.0 we need to install the free (but closed source) VirtualBox Extension Pack (NOT the "platform packages") from the VirtualBox download page. If you had installed VirtualBox from the repositories you have to make sure to choose the extension pack for the right version of VirtualBox. You can see the version of your installed VirtualBox in the help > About VirtualBox menu. For regular updates and bug fixes, it is recommended to install the most recent VirtualBox version from the Oracle repository.

All virtual machines need to be powered off before installing the extension.

2. Become a "vboxuser" in Host machine (local machine)

To be able to get access to an attached USB device, the Ubuntu host user needs to be in the vboxusers group. Add your user to this group by running the following command

sudo usermod -aG vboxusers 

and reboot or logout/login.

3. Activate USB support in VirtualBox Manager

Shut down your virtual machine and open USB settings in the VirtualBox Manager. Tick Enable USB Controllerand USB 2.0 (EHCI) Controller or USB 3.0 (xHCI) Controller.

If these settings are greyed out, you need to shut down the virtual machine.

4. Select host USB device for access from the guest

To grant access to USB devices we need to select a device to disable in the host and to enable in the guest (this is a precaution to avoid simultaneous access from host and guest). This can be done from the panel Devices menu or by right mouse click in the bottom panel of the VirtualBox Manager on the USB icon:

Tick the device you need in the guest, untick it if you need it in the host. If you can't see your USB device in that list, it means that VirtualBox cannot access your host USB devices. Make sure your user is added to the vboxusers group and that you restarted your host.

The selected device will immediately be accessible from the guest. A Windows guest may need additional drivers.

• Windows 7 needs an additional driver for USB 3.0 support.


• Windows 10 does not accept an NTFS formatted USB pen drive.

[optional] Use USB filters for permanent access in the guest

By defining USB filters we can define USB devices that will automatically be presented to the guest when booting the guest OS.

Click on the green + symbol on the right to add a known device.

Note, that some devices may lead to a boot failure of the guest. We can not use these devices for filters.
