I am having the same problem. Before I did anything I plugged the usb in to check the modules. One worked fine and the other doesn't. The computer sees it as a mouse but, I can tell that my pc is starting to lag. If I plug it in before I start the utility software it wont start. Soon as I unhook it, it opens up. Also, most of the leds the sensor bar were bent when I opened the box. In all honestly, Im not impressed with the packaging. I didnt spend my hard earned money on theses for them to show up broke.
