For use of USB in Virtual Box 3.x you need a PUEL-version. From Virtual Box > 4.x USB 1.0 is supported in the OSE version installed from software center. For USB 2.0 or USB 3.0 (from Virtual Box > 5.x) we need to install an extension pack free for download from Oracle. This will make our Virtual Box a PUEL-Version (see this question on details on how to install Virtual Box from the Oracle repository).
To change settings of a virtual machine needs the guest to be powered off.
To be able to get access to an attached USB device the Ubuntu host user needs to be in the vboxusers group. This can be done from Users and Groups after having installed the gnome-system-tools or from the command line by
sudo usermod -aG vboxusers <username>
We need a reboot or logout/login for group membership to take effect. On a Windows host a special kernel module will provide USB access.
We need to activate the virtual USB driver in our guest OS.
Note that we can only change these settings when the virtual machine is in shut down state.
In the USB settings from Virtual Box Manager tick "Enable USB Controller" For enabling the USB 2.0 driver also tick "Enable USB 2.0 (EHCI) Controller".
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 Virtual Box Manager on the USB icon:
Tick the device you need in the guest, untick it if you need it in the host. The selected device will immediately be accessible from the guest. A Windows guest may need additional drivers:
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.
Read more on USB support in the Virtual Box User Manual.
