I have installed this driver and windows7 seems happy with it. However, when I check the port address in the devices properties it comes up as" port#0001.hub#003". Ardunino does not recognize that, as it seems to want "PORT xx". Windows shows the type as "libusb-win32" whereas when I plug in an Arduino duemilanove, that shows up as PORTS (COM and LPT) and serial converter.
