VirtualBox Manager to show USB devices in use / bindings

[DrHouse]

With more than a few VMs, the exercise of finding the VM that has a device "in use" is a long exercise, especially where they are remembered over time such that devices that are re-attached physically are claimed by VMs without warning. It would be helpful to have a view, like the media manager, to see devices used by VM's. Even if this did not support change, the reporting of device<->vm mapping would be helpful. A simple list would suffice.
