USB CDC Class Driver

Hi All,
is this normal ? 

Using 103F along with ST USB CDC Libs on my board and it seems that the USB driver on the PC negotiates a new COM port for every new board i connect to the PC.

Normally this is not a problem but when the units are been tested, they are tested on one PC, thus that PC ends up with 100s of used COM ports.

Having worked with Microchip USB CDC all board would use the first instance of COM port that was negotiated.

Is there somthing i need to change in the libs to ensure the PC driver does not create a new COM port every time a new board is plugged in ?
