IN my office PC USB is automatically disabled. USB is showing up in device manager>disk drive bt in disabled mode. Now when i try to enabled it, it is automatically disable again in just one second. Again i will enable it and automatically will be disabled as soon as i click enabled. and USB is not showing up in mycomputer as well as in disk management. One more thing i also tried registry trick. I mean changing Hex value in USBSTOR.
Kindly suggest me something.
