Hello-
I'm not aware of any "unsupported drivers". However, http://www.ni.com/pdf/manuals/320427.pdf gives instructions on how to use this box. It might be possible to write a driver. However, this driver will not have a VISA passport, so most instrument drivers (ni.com/idnet) are useless. It's probably best to invest in a different controller.
