    Default USB device not recognized


    I am using Windows 8 Consumer Preview. Recently, I always get a message- USB device not recognized when I plug a USB device. Also, I can hear "tada" noise. The device manager shows it as an Unknown device.

    Is anyone experiencing this? Please help..

    Win CP is very out of date. Either Custom Install the newer Win 8 RP or wait until Oct. 26th and buy Win 8 Pro when it is released.

    Have you tested on another system? Since Windows 8 Consumer Preview is no longer supported, I would suggest you to upgrade to Windows 8 Release Preview.

    Uninstall and then reconnect the external hard drive

    This method resolves issues where the currently loaded USB driver has become unstable or corrupt.

    1. Click Start, type Device Manager in the Search box
    2. Click Device Manager from the returned list.
    3. Click Disk Drives from the list of hardware
    4. Right-click the USB external hard drive with the issue, and click Uninstall.
    5. After the hard drive is uninstalled, unplug the USB cable.
    6. Wait for 1 minute and then reconnect the USB cable. The driver should automatically load
    7. Check for the USB drive in Windows Explorer

    Note: Connecting your USB external hard drive into a non-powered USB hub can cause a lack of enough power to operate the external drive. Instead, plug it directly into your computer.

    This is not a fact of your USB or your USB serial port and even not in your USB's driver but this is the fault of your windows because of some viruses desaeses in your computer and your USB is not recognized proprely...
