Failed to access the USB subsystem.
VirtualBox is not currently allowed to access USB devices. You can change this by adding your user to the 'vboxusers' group. Please see the user manual for a more detailed explanation.
How do I add 'my user to the 'vboxusers' group?
What is the 'user' in this?
I have used my name to add to the vboxusres group in the system>Administration> Groups and Users, But it still shows the same message.
