Without more detail (what devices, what MFG, etc ) I can only guess but,  I think this might be what you are looking for

Jeff,

Sorry for the lack of details.

But what I would like, is a way to automaticlly reconfigure NI's "USB-6259"

Currently, when a USB-6259 is connected to my computer, MAX will asign a Device#.

each time a different USB-6259 is connected to the same computer, the Device# is incremented.

Which causes my VI not to work, unless I physically go into MAX and reconfigure the Device. 

So I'm hoping for a way to have labview automaticlly configure, each time I change my USB-6259.

Thank you

Have you tried renaming the device in MAX? I generally name my device. If I need to delete it or change it, I go into MAX and delete the device and rename the new one. The program refers to the device name and no changes to the program s needed.

Check the link in my first resonse----  You might be pleasantly rewarded   that API can reassign aliases (according to prophecy)

Hence my tag on the site "TryThis"  I haven't yet and would like some feedback.

Here is how I solved this issue for myDAQ, basically this function will generate the physical channel string for the first availible myDAQ (you can change this to other devices).

Perhaps you can use this as a starting point.

I have the same issue, the problem with the API is that it can only reassign an alias to a name not already being used in the system.

So if my newly connectly USB device is shown as 'Dev2' but I want it to be called 'Dev1' it doesn't work as you cant rename it to an existing name (the disconnected USB device). So frustrating!

Has anyone managed a workaround for this yet?

19,

Not yet,  although there have been Idea Exchange posts related to this.  For now you still need to use MAX>>Tools>NI VISA> VISA Options to manage Aliases for non connected USB Devices.  Just clear the old Alias (And Save) then the old Alias can be assigned to the new device.

When you see this screen you are in business

Hi Jeff,

As the customer I'm currently working for wanted the system to be as automated as possible I came up with this Community Example:

As it is only the revision there is plenty of room for improves, please comment on the Community post with ideas. A link to the Idea Exchange post relating to this subject would be helpful too! 

Thanks,
