To use FDM-SW2 you only need one USB connection, to the RX port. This carries spectrum info to your PC display and CAT commands (tune, band etc) back to your DUO.

You can use the other two USB connections TX (digital audio in/out) and CAT (internal USB <-> TTL logic) separately from, for example, WSJT program to control the DUO.

Hi Ian, did you use the full install version of SW2? Have you tried the drivers in http://sdr.eladit.com/FDM-DUO/Drivers/USB_CAT_PORT/index.php?lang=EN

A quick search of the message archive shows a fair number of messages about USB CAT drivers.  It should be an FTDI USB Serial converter, and create a COM port once the driver is recognised. Do you see any unknown or erroring devices?

Visitors arriving here, so tied up now, I'm sure others can help.

Best to include the firmware versions and SW2 version when asking for help, you can get the versions from menu 84 on the DUO.
