MATLAB: How to use Measurement Computing USB 31xx series hardware with Data Acquisition Toolbox 2.9 (R2006b)

Data Acquisition Toolboxmcc

I would like to use one of the following Measurement Computing boards with Data Acquisition Toolbox.
USB-3101
USB-3102
USB-3103
USB-3104
USB-3105
USB-3106
USB-3110
USB-3112
USB-3114

Best Answer

The Measurement Computing USB 31xx series devices are not supported by the Data Acquisition Toolbox.
To work around this issue, perform these steps to add support for these devices:
1. Quit MATLAB.
2. Find the following file:
$MATLABROOT\toolbox\daq\daq\private\mwmcc.ini
where $MATLABROOT is the MATLAB root installation directory obtained by issuing:
matlabroot
at the MATLAB Command Prompt.
3. Make a copy of this file and rename it to mwmcc.ini.old.
4. Open the file mwmcc.ini in a text editor, and add the following lines at the end of the file:
