Right out of the box everything worked fine through the USB connection. Games, YouTube, jRiver Media Center all worked just fine. Then I installed the nuprime driver and the IDA-8 disappeared from the world. The nuprime control panel reports no devices connected. I've tried unplugging / plugging the USB. I haven't tried deleting all my USB ports like one post said since that was over a year ago and USB 3 was not around. The optical port works ok and I don't have much 384kb files or DSD so I have to think nuprime simply doesn't care much about this issue.
