I'm trying to interface with a USB oscilloscope, the Handyscope HS3, through Matlab.
I got a basic interface working a few weeks ago but for some reason a library call now seems to cause Matlab to crash. I've been trying to debug this problem with the manufacturers example file.
The error occurs when trying to call:
Result = calllib( sDLL , 'InitInstrument' , 0 );
I first get an error
Warning: The data type 'FcnPtr' used by function SetDataReadyCallback does not exist.
> In loadlibrary (line 431)
Followed by a crash with the following stack trace.

Thank you for your help.
Based on previous threads I suspect that this is caused by the header file, however this is the first time I'm using an external library and I'm not knowledgable enough to know what to look for.
The only thing I've really figured out is that the crash doesn't occur if I try running the script without the oscilloscope plugged in. The instrument works fine while using the manufacturers propriety software though so that doesn't seem to be the problem.
The header file looks like this: (I've deleted the last part since it's just definitions of more library calls)
