I'm using matlab2015b(64bit) on windows7 and trying to get some reading from my NatianalInstruments USB-6009 using simulink. Using Labview I get data, so I know the device is working. In simulink I'm unable to find a Realtime block for this device. There are plenty PCI based NI solutions there, but no USB based. Could someone please point me in the right direction, I have been searching the last 4 hours on this site.
