I'm using ARCXT software with a BCT15X scanner and USB-1 Cable. The scanner comes with a serial port cable, unfortunately my computer doesn't have a serial port. I bought a USB-1 Cable from Amazon to overcome that. Apparently the computer doesn't have the right driver. I went through the Uniden/Scannermaster rabbit hole searching for the correct driver, but got nowhere. Any help is greatly appreciated. Marvin N5RKW
