How can I comunicate with a USB-D9 (male) & D25 (female) serial port converter?

I have a D9 (male) and D25 (Female) serial ports both connected to a USB cable as that in the attached picture. I tried to use this command: portSpec = FindSerialPort([], 1);

but matlab did not work:

Error using ==> FindSerialPort at 199

No ports found that match following default types(s) usa19 keyserial1 usbmodem usbserial

This is a list of the port(s) found: Bluetooth-Modem Bluetooth-PDA-Sync

Do you have any idea to comunicate with this device by matlab?

Thank you
