    Hi Michel Ghantous,

    Welcome to Microsoft Q&A!

    On modern Surface devices, including those with Snapdragon® X processors, USB4 uses the same physical connector as USB-C. That means they are not separate physical ports.

    From the image, you can see that Surface device has two physical ports, and each port is both USB-C and USB4 capable — you don’t have separate ports for each.

    To identify USB-C and USB4 ports on a Surface device with the Snapdragon X Series processor, you can look for the following characteristics:

    1. Port Design: Both USB-C and USB4 ports use the same physical connector type, which is a small, oval shape. This makes it challenging to visually differentiate them based solely on appearance.
    2. Specifications: Check the specifications of your device. USB4 ports support higher data transfer rates (up to 40 Gbps) compared to standard USB-C ports (which can vary, but USB 3.2 typically offers up to 20 Gbps). If your device supports USB4, it will be mentioned in the technical specifications.
    3. Functionality: USB4 ports are backward compatible with USB-C devices. If the port supports features like dual display output or higher power delivery, it is likely a USB4 port.
    4. Device Documentation: Refer to the device's user manual or technical specifications online, which will specify which ports are USB-C and which are USB4. For example, the Surface Laptop and Surface Pro devices with Snapdragon processors typically have USB-C/USB4 ports that support charging, data transfer, and video output.
    5. Labeling: Some devices may label the ports with icons indicating their capabilities, such as a lightning bolt for power delivery or a display icon for video output.

    By checking these aspects, you should be able to identify the USB-C and USB4 ports on your Surface device.
