Choose the option to look for it via Microsoft. Windows should alert you about the new hardware and give you an option on where to look for the driver. However, the easier path is to let windows automatically find and install the required drivers. The ECS cable is based on the FTDI chip and ECS gives the location of the driver. The first step is installing the software drivers so your USB port can emulate a COM port. Before buying the full version, I decided to try the free VCDS Lite version. I recently bought an ECS OBDII-USB cable with the intention of trying out Ross Tech VCDS software.
