I am trying to use a National Instruments USB6009 with Matlab(2012a on Windows 7) using the Data Acquisition Toolbox, but when I look at the device it does not register any available digital channels:

daq.getDevices

ans = 

ni: National Instruments USB-6009 (Device ID: 'Dev1')
Analog input subsystem supports:
    8 ranges supported
    Rates from 0.1 to 48000.0 scans/sec
    8 channels ('ai0','ai1','ai2','ai3','ai4','ai5','ai6','ai7')
    'Voltage' measurement type

 Analog output subsystem supports:
    0 to +5.0 Volts range
    Rates from 0.0 to 0.0 scans/sec
    2 channels ('ao0','ao1')
    'Voltage' measurement type

 Counter input subsystem supports:
    Rates from 0.0 to 0.0 scans/sec
    1 channel ('ctr0')
    'EdgeCount' measurement type

I know this device has digital channels. I have tried a backup USB 6008 and I get the same issue.

I have installed all the latest drivers from NI. I have also tried "addDigitalChannel" but I receive an error stating that this is not possible for the given daq.

Any thoughts or suggestions would be appreciated.

Thanks, Eric

This seems to be an issue with Matlab 2012a. Upgrading to 2013b has solved this issue and now Matlab recognizes the digital channels on the NI USB6008/6009 DAQs.

Hopefully this will be helpful should someone end up in the same situation.
