11 years agoDoes the Icon for unknown device disappered in the device Manager (the USB Blaster should show up as a device under "USB Controller")?
If you click on "Hardware Setup" in the programmer window does the USB Blaster show up (you need to choose it once to indicate which programmer to be used, even if there is just this one connected). If the USB Blaster shows up in the device manager but not in the programmer window, the JTAG Server seems to fail. There was a Problem with the Installation files for the IIRC 12.x Quartus Version if used as WebEdition on 64Bit OS. The webEdition was the 32Bit Version with the JTAG Server not starting under 64Bit OS. But this was fixed with 13.x...
