Today I tried to use my pen drive with my laptop and when I inserted the pen drive to that then it shows me the error message which says 'USB Not Recognized'. It was having the error code 43. I tried the same pen drive on another computer and there it was getting detected without any problem. This ensures that the problem is with the laptop and not the pen drive. Can you tell me that what the possible reason for the problem is? I will appreciate if anyone can help me with this.
