Error -50405 on USB 6008 Windows 7

[ogrant]

I am getting an error -50405 when reading from a USB 6008 on a Windows 7 enterprise machine.  I do not get this error on either of the two Windows XP machines I use.

Hello ogrant,

To better answer your questions, what NI DAQmx driver are you using? Does this error occur in Measurement & Automation Explorer (MAX) Test Panels? Have you tried the device on different USB ports?

Best regards,

Similar problem. And no, changing USB port didn't help.

The first thing that I need you to try is doing a self-test in Measurement and Automation Explorer.  If the device still fails there are a number of troubleshooting options that we can try.

• Reset the device from the driver (niScope_ResetDevice or DAQmxResetDevice).
• Open Measurement& Automation Explorer (MAX) and expand Devices and Interfaces to locate your device. Right-click the device in the list and select Reset Device.
• Disconnect and reconnect your device from the system.
• Reboot the system.

See if any of these work for you and let me know.

when usb 6008 plugged in first and recognised by max it is passing self tests and test panels are opening but when it comes to try it within a vi it is giving this error. After that self testing fails, trying to reset the device also makes the program stop responding. is it a driver problem or a windows 7 problem.

You can always upgrade to the newest DAQmx driver here, but the problem could also be in the configuration settings. Depending on what kind of task you are setting up, the software could be tying up some of the resources or timing out and throwing an error.

You are able to acquire/generate data from the MAX test panels, so I would start with creating a DAQmx task in MAX and see if you can run the task without error. If that's successful, try importing that task into LabVIEW or running an example program.

find with google search, is usb not plug and play in win 7?

[Jake_H]

It depends on how you define "plug-and-play". In this case, you need to have the DAQmx driver installed before Windows will recognize it. If you look at this article, the plug-and-play experience occurs after DAQmx has been installed. 

"The following sequence begins once you power on any (non-legacy) NI USB device and plug it into a PC on which NI-DAQmx has been installed."
