Bus Blaster JTAG debugger / Re: Bus Blaster 4.1 - Getting it to work
Even though the one I received is without mode jumper, I just used a bend attachment clip to short holes to simulate jumper on mode pins.
So far, update "buffer logic" is successful, and self-test is successful.

However, when attempting to connect to a developement board with JTAG port (JTAG port is working verfied by Lauterbach Trace32)

Since JTAG port and bus blaster v4.1a all supposed to be working, I wonder if it's the firmware that's not working?

The firmware I flahsed is from

And the binary comparison shows these two files are identical

I wonder it may mean that once flash with this firmware, bus blaster v4.1a can do nothing other than self-test??

Also, the last sentence on ... _resources
We highly recommend users upgrade to a non-selftest buffer immediately.

So it make me wonder I need to flash it with a "non-self test" firmware to make it work?

I also have the same problem.
I purchased Bus Blaster 4.1a from ebay.

However, I notice the one I received doesn't have mode jumper pins. Looks like all other people have mode jumper pins.
Can you take a picture of your board?
I don't know what the behaviour would be when without mode jumpers at all
