As support staff preparing for next term my college is using the Altera DE0 board with software 10.1sp1_quartus_free_windows.exe. Problem is I get the error “The hash for the file is not present...” when installing the USB-Blaster driver.

Is there an easier way to get this to work besides turning off secure boot? Is there a newer driver which has the hash that would work? It needs to be simple for the Students.

Hi, could you try this? the default JTAG clock frequency for the external USB-blaster II is 24M. Could you try reducing the JTAG clock speed to 16M or 6M to see how things go.

    I googled but could not see where to change the J-Tag frequency. But I realize I need to appologize because I may not have been clear enough.

    First, it looks like there is some kind of USB Blaster hardware which I am not using. I have just a standard USB cable which plugs into the DE0 board.

    Second, while windows sees the driver, Quartus says "No Hardware" as shown in the .attachment.

    Sorry for my missing details.
