    Welcome Paul Allison,

    Thanks for reaching out to Microsoft Q&A Forum. I understand that when you connect your Nikon Coolpix camera to your Windows 11 PC, you get the "USB device not recognized" error.

    To narrow this down, could you please share:

    • Which Coolpix model are you using?
    • Did this camera connect to this PC successfully before? If so, did the issue start after a recent Windows update or another change?

    Please make sure you already tried the Q&A Assist steps. In addition, please try the following:

    1, Turn off USB selective suspend

    • Open Control Panel, then Power Options. Next to your active plan, select Change plan settings, then Change advanced power settings.
    • Expand USB settings, then USB selective suspend setting, set it to Disabled and select Apply.

    2, Stop Windows from turning off USB hubs to save power

    • Open Device Manager and expand Universal Serial Bus controllers.
    • For each USB Root Hub entry, right-click it, select Properties, open the Power Management tab and clear Allow the computer to turn off this device to save power.

    3, Fully reset the USB ports

    • Open Control Panel, then Power Options, then Choose what the power buttons do. Select Change settings that are currently unavailable, clear Turn on fast startup and save the changes.
    • Shut down the PC and unplug it from power for about one minute. For a laptop, also unplug the charger. Then turn it back on and reconnect the camera.

    4, Reduce USB load on the PC

    • Disconnect any other USB devices you don't need, such as external drives, webcams or phones.
    • If your PC has a USB 2.0 port (often black), connect the camera to that port instead of a USB 3.x port.

    Looking forward to your update.

    Connect the powered-off COOLPIX directly to the PC with Nikon’s supplied USB cable, turn the camera on after connecting it, and avoid USB hubs; this is Nikon’s camera-specific procedure for the “USB device not recognized” error.^1^

    1. Rule out the connection first

    1. Turn the camera off and disconnect it.
    2. Ensure its battery is sufficiently charged.
    3. Connect the cable securely at both ends, preferably using the supplied Nikon cable.
    4. Plug it directly into another USB port on the computer—not a hub, dock, keyboard, or monitor.
    5. Turn the camera on and wait for Windows to detect it.
    6. If possible, test:
      • A different known-good data-capable USB cable.
      • The camera on another computer.

    If another cable works, replace the cable. If the camera fails on multiple computers and cables, use a memory-card reader to retrieve the photographs and contact Nikon support.

    2. Remove the failed USB entry

    If Windows still reports that the device is not recognized:

    1. Right-click Start and select Device Manager.
    2. Expand:
      • Universal Serial Bus controllers
      • Portable Devices
      • Cameras or Imaging devices
    3. Locate Unknown USB Device, the Nikon camera, or any entry with a yellow warning icon.
    4. Right-click it and select Properties.
    5. Note the message and error code under Device status. Microsoft recommends using this code to select the appropriate Device Manager repair.^2^
    6. Select Driver → Uninstall Device → Uninstall. Disconnect the camera first if Windows permits.
    7. In Device Manager, select Action → Scan for hardware changes, then restart Windows.
    8. Reconnect the camera using the direct-connection procedure above.

    Uninstalling the device entry does not delete photographs from the camera. Microsoft documents uninstalling the affected device and scanning for hardware changes as the driver-reinstallation procedure for several Device Manager errors.^3^

    3. Install Nikon software and available drivers

    Install the current NX Studio, which includes Nikon Transfer 2 and installs Nikon camera support components. Nikon lists NX Studio as compatible with Windows 11.^4^

    Obtain the current software, firmware, and model-specific instructions from Nikon’s Download Centre.^5^ After installation:

    1. Restart Windows.
    2. Start NX Studio or Nikon Transfer 2.
    3. Connect the powered-off camera directly to the PC.
    4. Turn it on and check whether Nikon Transfer detects it.

    Also check Settings → Windows Update → Advanced options → Optional updates. Install any relevant USB, chipset, or camera driver updates, then restart. Optional driver updates are not installed automatically.^6^

    Interpreting the result

    • Works with another cable: the original cable is faulty or charge-only.
    • Works in another port: the original port or attached hub is the issue.
    • Works on another PC only: install the PC manufacturer’s recommended chipset/USB drivers.
    • Still appears as “Unknown USB Device (Device Descriptor Request Failed)” with multiple cables and PCs: the camera’s USB connector or internal USB hardware may require Nikon service.
    • Photos are needed immediately: remove the memory card and use a compatible card reader.
