    Try these steps in order:

    1. Check whether the issue is with the cable or accessory.
      • Use the cable that came with the USB-C device if available.
      • Not all USB-C cables support charging or data transfer.
    2. Install the latest Surface drivers and firmware.
      • Open the Surface app.
      • Expand Help & support.
      • If updates are available, select Check for updates to open Windows Update and install them.
    3. If a USB-C adapter is involved, remove it and restart the Surface.
      • USB-C adapters do not have an on/off switch or LED indicator.
      • After restarting, reconnect the adapter and test again.
    4. If the USB-C device is not charging or not working on Surface Studio 2 or Surface Studio 2+, verify the correct behavior.
      • For charging a USB-C device from the Surface USB-C port, cable compatibility matters.
      • For powering the Surface Studio itself, the USB-C ports do not accept inbound power. Use the original power cord.
    5. If both USB-C ports still do not respond, open the Surface app, describe the problem, and select Get Help.
      • For business devices, contact the organization IT helpdesk or admin.
      • If hardware service is needed, use Microsoft authorized Surface repair options.

    Hi Marycarol Keena,

    In addition to the AI Answer's suggestions, you could try performing a forced restart of the Surface. Disconnect all USB-C devices, shut down the device, wait about 10 seconds, then press and hold the Power button for roughly 20 seconds until the Windows logo appears, disappears, and appears again. After Windows starts, test the USB-C ports again.

    You can also check Device Manager for any USB controller issues. Open Device Manager, expand Universal Serial Bus controllers, look for any warning icons and if present, uninstall the affected USB controller and restart the device. Windows should reinstall the driver automatically.

    Could you also let me know whether the USB-C ports were working normally before, and when you first noticed the issue? If the problem started after a recent Windows update, firmware update or other change, that information may help narrow down the cause.

    Please keep me updated on how it goes. If both USB-C ports still do not respond with multiple known-good devices and cables, we can look at the next steps.
