Utility to identify USB devices on VMs

Having a dozen VMs running and connecting USB devices back and forth it would be REALLY useful to have a tool, e.g. "Quick look" like utility, to quickly list and identify which USB devices are connected to what VMs. Now, to be sure, I have to check each one out.

A bonus feature would be the ability to quickly reconnect USB devices through that same interface between VMs.

I'm not sure which method is better identifying (trying to) multiple same kind devices; Numbering by insertion order or try to keep a static number based on serials and "unique" stuff (could be difficult on "all" devices w/o standardized serial/UUID specs?).

 

On a Linux host, when a virtual machine is running, its window is the active window. If you plug a USB device into the host system, the device connects to the virtual machine instead of the host by default. If a USB device connected to the host system does not connect to a virtual machine at power on, you must manually connect the device to the virtual machine. activation-process
