Question about COM ports

Hey I have a usb to serial adapter for use with Cisco routers and switches. Everytime I plug it in, it seems to choose a random COM port. Is there any way to make that device always use the same COM port.

OS: Windows 7 Ultimate

Is the device listed in the Printers and Devices window? If it is you should be able to set a com port as you would with a printer.

Was there any software included with the device?

Does it show in Device Manager and have an option to select a port?
