How to retrieve a 3rd party USB device's firmware revision?

[lamnk]

Hi,

I've installed a 3rd party USB device to NI-VISA and like to retrieve the device's firmware version on my Labwindow application. Is there a command that allows me to do so?

Given that the firmware version can be retrieve by windows in device manager, I like to find out if NI-VISA or Labwindow has the common function to retrieve the version info as well.

Thank you

Where are you finding the firmware information in device manager. I am only aware of being able to see the driver version in Device Manager.

I don't believe that there is any standard way for a USB device to specify a firmware version. This is implemented in a device specific manner (if implemented at all), so there is no single answer to your question.

Of course this is all assuming you are referring to a USB-RAW device in VISA. If this is a USBTMC instrument which VISA picks up automatically, then the firmware version should be one of the fields returned in response to a *IDN? query.
