A generic IrDA adapter won't work. You need the Cressi USB interface.

If a device is using infrared light for the communication, then that does not necessary mean it's also using the IrDA communication protocol! On the PC side, the Cressi interface is simply a standard (FTDI) usb-serial interface, and the proprietary infrared link to the dive computer sits behind it.
