If you go into the WIKI, under the USB dongle page is the link to the FTDI drivers. make sure that the dongle is unplugged and then download and install the USB driver. The lnk will put you on the correct page. Once the drivers are installed, plug the dongle back in and make sure that it installs the new drivers for the dongle. If not, then you may have to go into the hardware manager and remove the previous install of whatever generic driver Windows previously installed and then plug the USB dongle back in to get Windows to install the correct drivers. Once the correct drivers are installed and Windows tells you the com port it assigned to it, then you can use that infomation to properly configure LOR.
