    What is listed in device manager ?
  2. I'm not sure if you ever found the solution but I was having the same issue. After installing Windows 7 on a Sony Vaio, I ended up with a "System Base Device" and an "Unknown Device" listed in the Device Drivers. In my case it was the following:

    System Base Device - The Card Reader driver for Win 7.
    Unknown Device - Firmware Extension Parser (under System Components) for Win 7.

    Both available at the Sony website.

    Hope this helps you or anyone who is having the same issue.
  3. Thank directly from Brazil

    you is great
