I'm using 2012b and a USB2000 spectrometer, once I run the program it shows this:

Error using icdevice/connect (line 113)
An error occurred while executing the driver connect code.
Spectrometer not found, Please make sure the spectrometer is connected properly.
If this error is not an instrument error, use MIDEDIT to inspect the driver.

Error in demo_OceanOptics (line 24)
connect(spectrometerObj);

Any help ? Thanks

I have been using this driver for the Wavesurfer 104Xs-A. At apparently random times we could not connect to it. The problem was in the wrong buffersize for TCPIP at connect time. This is calculated dynamicaly, and is dependent on the settings of the scope. Our solution was to fix the TCP buffersize to 10 Mbytes in the connect function in the initialization and cleanup.

original code
set(interface, 'InputBufferSize', bufferSize);
set(interface, 'OutputBufferSize', bufferSize);

new code
set(interface, 'InputBufferSize', 1000000);
set(interface, 'OutputBufferSize', 1000000);

Depending on your hardware you may even need larger buffers.
