We're good, but we aren't Oracles
Did you try with a controller installed?
Did you try with more than one controller?
Which OS are you running?
Laptop or stationary?
How did you build the programmer?
Did you use a PCB?
Did you inspect the PCB with a magnifying glass before assembly?
Did you inspect the PCB with a magnifying glass after assembly?
Did you measure for connectivity where there should be and none where there shouldn't?
Did you try it on more than one PC?
Did you try more than one circuit?
Without this info, we'd just be guessing.
The answers you get will not be all that much better than the amount of work you put into your questions.
