Error USB2000 ocean optics Matlab toolbox

[Anrie]

Hi,

I am having an error trying to use the ocean optics USB2000.

I downloaded the Matlab toolbox and installed the Omni Driver. I followed the readme by adding path to classpath.txt and librarypath.txt but getting the error:

Error using instrument/delete (line 82)
Operation failed: An error occurred while executing the driver disconnect code.
OmniDriver was not found or could not be loaded. Possible reasons are javaclasspath.txt or classpath.txt is not configured
properly to load OmniDriver.
If this error is not an instrument error, use MIDEDIT to inspect the driver.

Error in icdevice (line 308)

HI Anrie,

The National Instruments forum will not be the right place to answer this question since this is not a product that we created or support. Look for support from The Mathworks Inc.
