I've installed the R200 on two computers but can't get it to work with an application. Both computers have USB 3.0 ports and one is Windows 7 and the other is Windows 8.1 (Surface Pro 3). The app I'm trying in Z Vector Touch. I've tried another one had has a similar error message. The driver installation didn't go smoothly but after a few attempts it seemed to be fine. I do see the R200 in my device manager list by the way. Any advice? Do I have a broken device?
