With USB-Blaster, It works on Quartuss II for Program/Verify, but with USB-Blaster II, it does not work due to an error message "cannot recognize Silicon ID for Device 1"

Hi,

If your PC has already set the environment then you should be able to directly performed "jtagconfig --setparam 1 JtagClock 6M" in the terminal or command prompt. This is assume you are only connecting 1 blaster.
