ok, since my laptop doesn't have the right connection to pin on the plug, I ordered the usb adaptor. . .and whenever I start the program up to connect to my car, with the key in the ignition turned on, it says failure to connect. . .

How do we connect to the car through the usb port. . .is there a place on the program that will allow me to designate the usb port as the port throughwhich I want the reader to scan?

It says that there's a failure to find an obd2 device or something. . .???
