I downloaded the extension for LUFA in AS7 and built it for the AT90USBKEY2, which I think is what its written for. It builds fine but when I uploaded it and plugged it in the device enumerates as Unknown and windows gives me an error that it thinks the device has malfunctioned. The example I built was Virtual Serial CDC Device Demo (Class Driver APIs). I'm just wondering if I'm missing something.
I built a project example also (USB to serial converter) and windows recognized that when I plugged it in but it was missing the driver, is that the problem for the first example?
