About Video Capture Adapter Driver:

TV Tuner drivers act as a communication bridge between your TV tuner and your personal computer. Whether you are using an external or an internal TV Tuner, it is very important that you update your drivers as often as possible in order to use your device at its maximum potential.
When bugs are found in the software, developers launch new drivers meant to solve these issues and improve compatibility with newer operating systems, as well as add new features to the device.
Usually, TV tuner drivers come as part of a package that also contains the video playback software. This way, users get to enjoy a more stable, bug-free experience, but also an improved user interface for the included playback software.
Most of the times, TV Tuner drivers come in an easy to use installation software bundle which guides the user through all the steps, but that’s not always the case: there are situations in which, with older devices, the driver must be added manually.
Before clicking the download button, please make sure that you have selected the appropriate driver for your unit and operating system. Don’t forget to check with our website for the latest drivers and software in order to keep your device up to date and running smoothly.

I was trying to hack a USB flash drive encrypted and protected by --- when I learnt a number of things about USB flash drives:
  1. All USB flash drives have few main components
    1. The flash memory chips that store the data
    2. The controller that:
      1. Allows access to the data
      2. Lets any OS understand the kind of device being used
  2. Certain controllers can be manipulated to:
    1. Create partitions
    2. Hide partitions
    3. Decided Disk encoding (EXT3FS, FATX, FAT32, HFS, ZFS, ....you name it...)
    4. Encrypt content
    5. Masquerade (across OSes) as different type of storage devices (e.g. a CD-ROM)
Now all this sounds quite terribly dreary but really helps understand the steps that I followed:

Drivers SMI USB Devices
  1. Unplugged all other devices from USB ports
  2. Plugged in the dead device...
    and made sure that it was detected and that the OS had loaded at least the mass storage device drivers.
    At this stage, if I tried to access the device or even format it, all I got was an error that told me that the OS could not read the memory on the device ...
    OS Access error

  3. To figure out the:
    1. The exact controller chip used
    2. The memory chips used
    3. State of the controller and the memory chips
      I downloaded and ran Chip Genius
      (You could download this software from:
      I told me that this device had a Silicon Motion SM3255AB controller
      Chip Genius to identify the controller

  4. Next, I downloaded the SMI 3255AB controller tool from http://dl.mydigit.net/special/up/smi.html
    (If you have a different controller you'll have to search and get the relevant controller)
  5. Running the tool I could see that the memory was accessible and so I could now try flashing the controller back to a default state.
    SMI Controller Tool - Initial Interface
  6. Next I clicked the space bar to run the tool and it ran a pretest and formatted the drive thus...
    SMI Controller Tool - Flashing
    SMI Controller Tool - Flashing Complete

    OS has remounted the device and shows it empty and functional
  7. Now, I wanted to make a few low level changes so I clicked Settings (Password in most SMI controller tools is 320) and here is what you would see... (Click Ok once you are done tweaking and then run the flashing process again. Be careful and aware of what you do since it can do nasty things to the device :) )
