Get Your USB Drives To Work With VirtualBox (Ubuntu Host) To get USB drives to work with VirtualBox when using Ubuntu as a host, you need to add your user to the vboxusers group.
Please note that this doesn't work with VirtualBox OSE, so you'll need to install VirtualBox 4.0.x from its repository. To add your username to the vboxusers group in Ubuntu, go to System > Administration > Users and Groups, click on "Manage groups", scroll down to the "vboxusers" group and click "Propreties", then check the box next to your username and click OK: "Users and groups" is not installed by default in Ubuntu 11.10, 12.04 and newer, so you'll have to install it firstly: sudo apt-get install gnome-system-tools Then log out and log back in, plug in an USB stick (or whatever you may need), start a VirtualBox machine and select the USB device in the lower right. If you want to set up USB for VirtualBox manually, you can run the following command: sudo gedit /etc/group.

8 Ways to Tweak and Configure Sudo on Ubuntu. Like most things on Linux, the sudo command is very configurable.
You can have sudo run specific commands without asking for a password, restrict specific users to only approved commands, log commands run with sudo, and more. The sudo command’s behavior is controlled by the /etc/sudoers file on your system. This command must be edited with the visudo command, which performs syntax-checking to ensure you don’t accidentally break the file. Specify Users With Sudo Permissions The user account you create while installing Ubuntu is marked as an Administrator account, which means it can use sudo. You can control user account types graphically from Ubuntu’s User Accounts tool.
