Not exactly. Windows assigns COM port number to pair "USB port + Adapter
serial number". So if you plug same adapter to the same USB port it set
the same COM port number. :)

And if you overloaded with adapter instances, you could delete unused ones
in Device Manager. And thier COM port numbers will be freed and used
if you plug other adapter or the same adapter to other port.
