Problem with USB 9233 - 50405

Hi Justin,


I am new to Labview - could  I get some example code to do this?


I have an issue with 6009 that always falls over on Windows 7, I have tried reset the ADC using the reset VI but that does not work. However, enabling and disabling it through device manager does.


Many thanks,

Hi, Is the below part solved?


"5.)  The NI 9172 chassis must be reset immediately upon receiving the -50405 error.  If self-test is called first, the chassis will have to be unplugged and replugged, this is a software bug on our part that has already been identified."

I have the error on a new USB module that I bought mid-2013, same issue as before. Mine is due to environmental noise - in one case, a motor turning on & off, and in another, proximity to a spark gap.

No other devices are having problems, just the USB. It is very sensitive to noise.

Re-routing cables helps, but nothing seems to cure it, not even the use of cables with embedded ferrites.

If anyone has another idea to try, please post. I am recommending that we look into alternatives for future purchases. This problem is maddening.
