interface PS joystick with matlab

Hi all,

I am trying to connect PS controller with matlab i tried the code

if true
  % code
arduino=serial('PORT_#0002.HUB_#0003','BaudRate',9600);
fopen(arduino);
fprintf('%s\n',fscanf(arduino,'%d'));
end
end

I got error "Open failed: Port: PORT_#0002.HUB_#0003 is not available. No ports are available."

when i write "instrfindall" it's status is closed is it the reason ?! or what ??
