Driver DAQmx 14.1 installed but not seen by USB 6221

Hello,

After a week fighting to install DAQmx driver on my Labview 2013 (Win XP), i finally got it with NI DAQmx 14.1.

Everything is okay, i can run my VIs.

But, when i connect my NI USB-6221 (BNC) nothing happens.

I checked in MAX if it was communicating, MAX see the device but says that the device's drivers are not installed.

Then I checked if there was other drivers for this device on the website ans apparently no, it runs with DAQmx.

Have someone got a solution ?

Thank you

Sorry for my English speaking, i'm coming from France.

The descriptions I see say that USB-6221 is a legacy device.  That probably means support for it in later versions of DAQmx have been dropped.

I found this  http://sine.ni.com/psp/app/doc/p/id/psp-84/lang/en 

It doesn't definitively say what versions of DAQmx support the device, but that list appears to only go up to version 9.8.

Thanks for your answer.

In this document it seems that it should work : http://download.ni.com/support/softlib/multifunction_daq/nidaqmx/14.1/readme_fra.html

But maybe I should try with version 9...

You're right.  That does show support for the USB 6221.

Make sure you've rebooted your PC.  Other than that, assuming you had no odd error messages during the installation, I don't know why it wouldn't work.  Unless by some chance that readme document is wrong.

Okay, problem solved with DAQmx v9.8 !

Thanks a lot !
