K8055 Not Recognized by Computer

My card will not be recognized by the computer. I copied K8955D.DLL to the proper location but when I connect the board it is not accepted. Thanks for any guidance.

Does the LED LD8 flash two times and stay on?
If yes, there may be some assembly fault on the K8055 board.

Thanks for the suggestion - I have actually solved the problem - the USB cable I was using had a fault!
