Step 3: Plug in your cable
Now you need to plug in your VAG-COM 409.1 KKL USB cable to your computer's USB port. You should hear a sound indicating that a new device has been detected. If you have not installed any driver for your cable before, Windows will try to find one automatically. However, it may not be able to find the correct one, so you need to cancel the automatic installation and proceed with the manual installation.
Step 4: Update the driver manually
To update the driver manually, you need to open the Device Manager on your computer. You can do this by clicking on the Start button and typing \"device manager\" in the search box. Then click on the Device Manager icon that appears in the results.
In the Device Manager window, you should see a list of devices connected to your computer. Look for a device called \"USB Serial Port\" or \"USB Serial Converter\" under the \"Ports (COM & LPT)\" category. It may have a yellow exclamation mark next to it, indicating that there is a problem with the driver.
Right-click on the device and choose \"Update Driver Software\" from the menu. A wizard will appear asking you how you want to search for the driver software. Choose \"Browse my computer for driver software\" and then click on \"Browse\". Navigate to the folder where you extracted the VAGCOM4091USBDriver files and select it. Then click on \"OK\" and \"Next\". Windows will start installing the driver for your cable.
Step 5: Check the COM port number
After the driver installation is complete, you need to check the COM port number assigned to your cable. This is important because some third-party applications that work with VAG-COM 409.1 may only support certain COM port numbers.
To check the COM port number, go back to the Device Manager window and double-click on the \"USB Serial Port\" or \"USB Serial Converter\" device under the \"Ports (COM & LPT)\" category. A properties window will open. Click on the \"Port Settings\" tab and then on the \"Advanced\" button.
