USB device interfacing with LabVIEW

[Bazgha]

Hello, I am doing interfacing of FTDI's FIFO to USB converter's(FT600) interfacing with LabVIEW. I have made block diagram attached for this purpose and I am able to get it's name in LabVIEW but I am unable to read data from it. Can anybody help me in ?

These are the DLL functions I have used in the above attached VI

Do you get any error message? Did you try to run your VI with highligt execution in order to determine when exactly the problem arises? Is the device visible in VISA and can you operate it?

[Bazgha]

No I don't get  any error sort of error. And device is visible in NI-MAX and NI VISA Driver wizard.I don't know what do you mean by visibility of device in VISA.

Somebody Please help me regarding my earlier messages . I really need to do communication with my USB device but I am unable to do so and I am not recieving any sort of errors as well

I assumed you have The Programming Manual for your USB Device.

You can try to read the programming  Manual of your USB before you proceed to coding.. then try experimenting to what the programming manual said.

I have the programming manual but it explains coding in C++ and  i have no knowledge of this language so taking help from it I tried to build DLL functions on LabVIEW but I am unable to read data from my device using those dll functions. Can you please check them for me. I have sent them earlier on this forum

here is the link of that manual
