Repeatable COM Port Enumeration
When the computer enumerates its USB peripherals it assigns COM port numbers to the devices in ascending order as it detects them: this means that the COM port number of each board needs to be set manually each time in the corresponding software. It would be much more convenient if each physical USB port on the PC always corresponded to the same COM port number. Luckily, there is a way to do this.
