Making connection to hardware using MATLAB - matlab

Question

I'm trying to make a connection to hardware (a controller of a moving stage) from Physik Insrumente using MATLAB. However, I have tried using the code that the company provided but did not work, so I have simplified but still doesn't work.
Here is my code:
addpath ( 'C:\Users\Public\PI\PI_MATLAB_Driver_GCS2' );
Controller = PI_GCS_Controller();
controllerSerialNumber = '118011005';
C867 = Controller.ConnectUSB(controllerSerialNumber);
display(C867.qIDN())
I am getting this error message:
PI_MATLAB_Driver_GCS2 loaded successfully.
Error using PI_GCS_Controller/ConnectUSB (line 17)
There is no interface or DLL handle with the given ID
Error in PI_GCS_Controller/ConnectUSB (line 17)
error(szDesc);
Error in PI_GCS_Controller/subsref (line 46)
varargout{1} = feval(fun,c,par{1});
Error in Untitled (line 5)
C867 = Controller.ConnectUSB(controllerSerialNumber);
ConnectUSB is:
function [c] = ConnectUSB(c,szIdentifier)
FunctionName = 'PI_ConnectUSB';
if(any(strcmp(FunctionName,c.dllfunctions)))
if(nargin<2), szIdentifier = blanks(5000); end,
try
[c.ID, szIdentifier] = calllib(c.libalias,FunctionName,szIdentifier);
if(c.ID<0)
iError = GetError(c);
szDesc = TranslateError(c,iError);
error(szDesc);
end
catch
rethrow(lasterror);
end
else
error('%s not found',FunctionName);
end
How can I connect to this controller?
