    Hello, as in the subject I have the Vag kkl interface, car diagnostics and it only uses COM1, COM2, COM3, or COM4 ports and needs one of these ports to choose, but I can't because I don't have it in the device manager, I don't know if this laptop or windows fault. My equipment is Sony PCG-7Y2L with Windows XP installed.

    Show the screenshot from the device manager - the interface probably has no driver installed, after a correct installation a virtual COM port should appear.

    After all, the ports are detected in the Manager.

    It doesn't have to, Vag kkl connects to USB.

    The author probably does not quite know what he does.

    Vag kkl works only on ports com 1, com 2, com 3, com 4, and one of these I have to choose in the device manager otherwise I will not connect the interface with the car.

    Now there are ports and before they were gone I don't know why.

    Added after 46 [minutes]:

    Yes, only now I have ports in the manager. But when I connect the Vag kkl cable I can't see it in the ports and in the USB serial converter an exclamation point pops up.

    You must install the driver.

    And don't worry about these COM ports from Device Manager.

    This is not about ports on the computer because they are emulated anyway.

    Upload screen from the application to this interface - where you have settings.

    I chose each of the ports and after clicking the test error with the port
    I understand the interface must be connected to the car but the port should write ok because it was on a friend's laptop.

    You need to install the drivers for the converter, only then you will have a com port with vag, which you must select in the program.

    Enter the ID of this "USB Serial Converter" from the manager (PID and VID).
