Inability about connecting a USB2 Device in Matlab Instrument control toolbox

I am able to connect and run fopen on a GPIB based instrument but not on a USB2 port based Instrument in Matlab control toolbox; Both of them are visible by "tmtool" and I can run query ("*IDN?")on the USB2 based instrument.

Details attached below - as you can see I can fopen the GPIB based instrument (address 9) but not the instrument with address: USB0::0x0957::0x4D18::MY54030016::INSTR. They both are under NI VISA.

Can anyone tell me if the format creating this USB2 based device object should be different?

>> vhwinfo = instrhwinfo('visa','ni')
