I'm normally a linux guy, and not so familiar with all of the USB stuff these days under Windows 7. I have an HP laptop running Windows 7, which I'm going to use with my Argentum until such time as the linux software is released. I got my electronics assembled, and when I plug my Argentum into the laptop, I get an "Unknown device". The instructions don't mention installing any drivers, but my recollection is that this is typically required. The Unknown device has a VID of 2341 and a PID of 0042. VID 2341 corresponds to Arduino, so the board is being recognized. What .inf file (or other procedure) do I need to follow to get the serial port driver installed?
