If this happens frequently enough, it is possible that all of the free or available com ports become reserved and the system is exhausted of COM portsВ as there is a limit. Occasionally, multiple com ports will be classified as reserved or 'in use' even though there is not aВ COM device or a USB device currently associated with it. This ensures that there are no conflicts when two of the devices are attached at the same time. A new device gets the first free or available COM port number.

If this device is connected again, the reserved port is re-assigned to it. Each time when you connect a new COM device or a USB device (true for modems, smartphones, Bluetooth, serial-to-USB converters, etc.), Windows detects it using Plug-n-Play and assigns it aВ COM port number in the range of 1 to 255.
