USB Mass Storage Error Code 10


  • Hi, I have Windows 7 Home Premium 64-bit and a 500GB Cavalry external HD.  I just built my system and I'm pretty sure that I've installed all of the relevant drivers.  However, this one issue has been troubling me.

    This is what I see when I plug my HD to the USB port:

    #1 is what I see in my Devices and Printers Window

    #2 is what I see in my Device Manager

    #3 is what I see when I go to the device properties

    I've tried uninstalling and reinstalling to no avail.  Can anyone help me?  Thank you...

  • Hi,

    If the hard drive is connected to a USB hub, please bypass it and connect to computer directly. You can also use the above steps to reinstall USB controllers.

    You can also try the following steps:

    Modify the Registry
    1. Click the Start Button, type "regedit" (without quotation marks) in the Start Search box and then press ENTER.
    2. Navigate to the following key:

    3. Right click the {36FC9E60-C465-11CF-8056-444553540000} entry, choose "Export", select Desktop in the Save in box and type backup in File Name. Click Save.
    Please Note: The backup file is on the Desktop and named backup.reg. We can simply restore the registry by double-clicking the backup.reg file.
    4. Highlight this key ({36FC9E60-C465-11CF-8056-444553540000}), on the right pane, and then check if Upperfilters and Lowerfilters value are present. If so, please right click on the values and select "Delete" to remove them.
    5. Restart the computer
