I had the same problem with error code 43 and I've contacted the Rode support. They were very helpful and suggested to change the USB cable. I had another one from my little label printer and voilà - it worked. It recognised my device and installed the mic. The weird thing is, that the old USB cable worked perfectly with my old laptop, but not with the new one.
I was pretty disappointed at first, because none of the other tipps on the internet had worked. And it was so simple. :)
