How are the COM Ports for My USB Serial Device Assigned?
I'm using an USB serial device like the USB-232. When I plug in my device, I always get the same COM ports assigned to it. If I plug in a second USB-232, it is assigned different ports, even if the first USB-232 is not still plugged in. Why does that happen? How are the ports assigned?
