Morpheus_79.Makes sense that the alternatives are all over the place, haha
Again, thanks for all the info. Didn’t realize the world of USB Blasters was so dense. Might be helpful to build my own just so I know all the things that can go wrong and better debug in the future.
You have NO idea 😉 …
There are some “ancient” DIY USB-Blaster projects out there in the wild… like this Japanese one from 2009:

It’s essentially not that complicated to build a USB-Blaster clone – you only need a programmable microcontroller with USB interface and some passive components. Everything else “just” lies in your skills in understanding JTAG and USB communication and in programming 😉 …
EDIT:
I just saw that Doug Brown just recently had a new blogpost about fixing your USB-Blaster Linux problem 😉 :
Ironically you need another functioning USB-Blaster zu flash the modified firmware onto it 😀 :
