9 years agoI found another thread here:
http://www.alteraforum.com/forum/showthread.php?t=48780 stating that the main difference between the two modules is that the USB-Blaster uses a fixed 6M frequency on the TCK, while the newer USB-Blaster II is configurable, but defaults to 24M. It also noted that the frequency can be changed with this command (located in your Quartus bin directory): jtagconfig --setparam USB-BlasterII JtagClock <#> So, as an experiment, I changed the frequency back to 6M, and it now works with the newer USB-Blaster II! So I am happy now, and can get back to work. Hopefully you find this helpful, and can avoid spending a morning chasing this down like I just did....
