Edit:
We also just tested it over usb by plugging it into the roborio usb port. No luck with that either.

I'm not sure why you're getting this error connecting to the sensor using LabVIEW.

However, we can send another board and have you return the one you've got - if you'd like to do that, please contact support@kauailabs.com with a reference to this chiefdelphi post and we'll get you started on that. I'm a bit concerned that since the board is passing all of our usual "is it ok" tests - and thus that even after replacing the board you'll still see the issue you're seeing now accessing it from LabVIEW - but am happy to process the swap for you.
