    Good morning Tiwari.

    I have tried all the options and none of them work.

    If I point windows to the drivers folder tu update it, the following message appears:

    It never shows up as USB Blaster II, always as Unknown USB Device (Device Descriptor Request Failed). Also in Windows 10.

    I have also tried on a Windows 7 PC and similar messages appeared. Unknown USB Device and not being able to manually install the downloaded driver

    Is it possible that the device is damaged?

    Thank you
