BagleBone doesn't show up as a USB device

I’m having trouble connecting to my beaglebone through ssh. I’ve verified that other computers can see it and that it’s booting properly but my computer doesn’t even see it as a listed USB device when I plug it in.

I’m running 64 Bit windows 8.1 and have installed all the beaglebone drivers and still have no luck. Anyone have any ideas? We’re using these for the intro to robotics class I’m teaching and several students are having similar problems. Linux seems to have no issues, but most of my students are only running linux in virtual machines which would bring a whole host of different headaches.
