    Dear @Janamatti, Priyanka,

    Thank you for posting your question in the Microsoft Q&A forum.

    We apologize for any inconvenience you may encounter when using our services/ products. Based on your description, kindly try these following steps:

    Install all Windows and Surface driver/firmware updates

    • Windows Update: Install all Quality and Optional updates, especially the ones labeled Surface in Driver updates.
      • Settings > Windows Update > Check for updates
      • Then View optional updates and install everything Surface‑related.
    • Surface app health check: Open the Surface app > Device information to confirm drivers/firmware are current. If they are not, follow the Download drivers and firmware for Surface - Microsoft Support guidance.
    • If you use a Surface Dock or USB4/Thunderbolt dock:
      • Confirm your dock is compatible with your specific Surface Laptop model and update its dock firmware.

    Reinstall USB/USB4 controllers

    • Navigate to Device Manager > Universal Serial Bus controllers and USB4™ Host Router (if present).
    • Right‑click each USB Root Hub (USB 3.0/3.1) and USB4 controller > Uninstall device (do not delete driver files).
