DAQ Toolbox use with two NI-USB-6009 devices

Asked by Seth
on 18 Mar 2011
I am attempting to use two NI-USB-6009 devices for a project, however I can only access one (whichever device was connected to the computer first). Whether the first device, second device or both devices are connected, DAQHWINFO('nidaq') returns the same AdaptorName (nidaq), BoardName (USB-6009) and InstalledBoardId (Dev1).
Using NI's Measurement & Automation Explorer/Test Panels, the two devices show up as 'Dev1' and 'Dev2' and are both accessible. However Matlab returns 'Dev2' as an invalid device ID.
Any assistance in solving this problem would be greatly appreciated.
Thanks, Seth

What version of MATLAB are you using? I'm guessing you've restarted MATLAB.
It should work...We'll figure it out.

I'm using R2010a. I've tried restarting Matlab, the machine, using a different machine, etc.

After reinstalling Matlab, it started to work. Thanks for your interest.
