Record from XDJ RX2 to computer

I want to know how can I record straight from my XDJ RX2 to a computer software. I have installed all drivers and updated versions. In Audacity (my favorite) the XDJ RX! is not recognized as an input source (as I can do with the DJM 450). Same happens with the Rekordbox app, that does not appear as "choice".

Is there a way to record to the computer using the usb cable as an output (as done on the DJM 450). Or the only way to record a mix out of my XDJ RX2 is directly to the internal USB?

I have tried all possible ways, but seems strange that neither Audacity or Recordbox recognizes the device, although all drivers are installed.

Thanks for the help
