Problems with USB device when using WindowsNT

[emmerte]

Hi,

my problem is that I want to use a simulator which can only be connected with USB to the computer.

I used the VISA Driver Development Wizard as discribed in this link (http://zone.ni.com/devzone/conceptd.nsf/webmain/6792BAB18242082786256DD7006B6416) and it didn't work.

I'm using Windows NT and VISA 3.1 and I read that it isn't possible to create a USB connection with VISA when using Windows NT. So my questions

1) is this right

2) Has someone a idea what I can do? I tried to use VISA USB Control and this also didn't work.

I hope I discribed my problem detailed enough. It's my first post.

Thanks for your responses

Joerg

once again me

I've forgotten to discribe the problem.

When I've created the .inf file and I try to install the file, the message " installation failed" appears but a .pnf file was created.

Thanks

Joerg

As you can see in this table, USB is not supported by VISA under NT:

I would recommend to use Win2000 or XP. Using one of these OSes you could use this turorial  to create your VISA-driver:

If it is not posssible to change the OS, you have to look for other ways of programming your usb-device. Check the web or the Microsoft site for help concerning Windows SDK and USB.

Hope this helps a little!
