Hello!

Depending on what class your USB device belongs to, you should be able to communicate with it using NI-VISA. To download NI-VISA, take a look at this link for the apprpriate version for your Operating System. You'll need the full version (under the "Drivers" section). Hope this helps. Thanks!

Thanks for valuable link.

               You mentioned that instead of direct usb, I can use NI-USB, but our customer needs direct communication through usb only, he may not agree to purchase this hardware. If there is any other possibility for communicating Device through USB by using its driver, please suggest me.

                Here I am sending attachment of that instrument which I want to communicate with PC. This instrument is actually made for plotting the graphs. It is not a data logger but it is part of my project....

                Waiting for positive reply....

There is no such thing as NI-USB. There is NI-VISA which is software and the link talks about using this software to communicate to a USB device when a driver does not already exist. In the pdf file you posted, it states that LabVIEW drivers are shipped with the instrument. If you didn't get them, you need to contact the vendor. If you have the driver and it doesn't work, then you should also contact the vendor as it is their software or if you want to post here, explain exactly what the problem is. Include error codes, screen shots, etc.

            I'm sorry for asking such silly question. When I read whole file (the one you suggested), then I come to know about NI-USB. Now I will try to work on it and upto how much level I get success, will inform you.

            But in future if I face any problem in my project, please help me.

            Thanking you.

Hi,

           I'm having LabVIEW 6, in which niviusb.dll is not present, According to my knowledge to develope driver for USB connected device, this file is required. As Here I'm sending 2 images which will clear the point.

           As for developing drivers, VISA Device driver developer should give option of PXI, VXI & USB. But it is directly going to the PXI option default  As I know it is happening because, it is having PXI dll available, but please suggest me how to go to Fig-1.

          I do think, it will solve my problem.

          Thanking You...

I'm confused. The pdf file you posted with information about the instrument said a LabVIEW driver was available from the vendor.

When you started the wizard, did you click the USB radio button? What version of NI-VISA do you have?

And, before you go down this road with the driver wizard, do you have information from the vendor as to the type of device it is. Unless the instrument is USB-TMC, you will need very detailed low level information from the vendor. Do you have any reference to the instrument's USB connection that you can post or provide a link?

Good Morning Sir,

            Because of improper communication from my side, I made you somewhat confused. Sorry for that. Here Now I'm giving you whole project idea so that, you will understand why I was asking such questions.!!

            This file is self explanatory, But really thanks for those replies.

            Waiting for reply................Really Thank You.

Well, you have provided an explanation of what your project is but that doesn't help. You original qustion dealt with how to control a USB device with LabVIEW. As I have asked before, the information that you provided from the vendor says a LabVIEW driver is available from them. Please just answer these simple questions. Do you or do you not have a driver from the vendor? If you do, what problem are you having with it. If you do not, have you contacted the vendor of the instrument to get one? If you cannot get a LabVIEW driver, you will still need to get a lot of information from the vendor. Any information you can provide that the vendor has given you about programming their instrument can help point you in the right direction.
