It came sealed in an NI box and has the correct serial and everything, but when physically opened the adapter, there's indeed not what's supposed to be there. A CBM9002A-100 (Corebai) and a APM32F407VET6 (Geehy). I got it working though, but indeed, the code introduced would be specific for a cloned version, not for the real NI adapter.
Workaround for HP/Agilent 34401A
