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.

VirtualBox failed to access the USB subsystem


Hello Derek,

Good Day!

By using

Usermod -Gvboxusers

is not advisable because it will delete your user from several groups except vboxusers. You are required to use

usermod -a -G vboxusers

If you are encounter an error that says cannot lock or group, you may use sudo to perform the command.

Hope this may helped you.
