USB-Blaster II devices, how to distinguish?

Dear Yuan,

I picked up again, after being idle for quite some time.

Thanks for your answer, it helped but I am still kind of struggling with it. Could you explain what happens below? It looks like jtagconfig changes the usb device type/identifier?

I'm puzzled somewhat.
