    USB Device Not Recognized Device Descriptor Request Failed


    When my girlfriend connects external USB device to any of the USB ports on Windows 10 Home she gets message:
    USB Device Not Recognized.
    She can not charge USB device via USB port.
    I went to device manager and under USB Controllers I see following:
    Unknown USB Device ( Device Descriptor Request Failed).
    I tried some tricks I googled for this message but none of them returned result.
    She didn't get any of the drivers with this device which needs to charge.
    What should I do to be able to charge this device via USB?

    Try the device on a different USB port. This will figure out if problem is caused by a broken port.
    Connect the device to another PC. This will figure out if the external device has problem.

    Open Device Manager and expand category Universal Serial Bus Controllers and locate the USB device which is not being recognized by Windows.

    Right-click on the device and select Uninstall from the context menu.

    After finishing the uninstallation, restart your PC then Windows will reinstall the device automatically.

    The problem can be caused by faulty USB driver. In this case, updating driver would fix the problem.

    Obtaining Hardware ID's to help Identify Hardware
    - Go to Start and type in "devmgmt.msc" (without the quotes) and press Enter
    - Expand the "Unknown USB Device" category by clicking on the + sign to the left of it
    - Right click on the "Unknown device" (if there's more than one, do this for all of them) and select Properties.
    - Then select the Details tab.
    - In the dropdown box, select "Hardware IDs" - and match the info to one of the following descriptions:
    - - If the Hardware IDs description contains VEN_ and DEV_, then let us know the 4 characters immediately after the VEN_ and the 4 characters immediately after the DEV_
    this is a PCI device and we'll look up the information at http://www.pcidatabase.com
    - - If the Hardware IDs description contains VID_ and PID_, then let us know the 4 characters immediately after the VID_ and the 4 characters immediately after the PID_
    this is a USB device and we'll look up the information at http://www.linux-usb.org/usb.ids
    If you don't have those items in the Hardware IDs description, copy down the entire string of the first entry and include that with your next post.

    Is the external device working with different computer?
