When i connect it to my pc , it does not detect the programmer giving a "USB device not recognized" error.
I dont think that there are any hardware errors in my circuit. I cant understand why the circuit does not work.
Also in our college many people have tried building USB programmers for PIC as well as AVR. Unfortunately only 1 out of 5 work. Most of them have the same problem.
Programmers brought from commercial firms also do not work .
Do we need extra precaution while building a USB programmer ?
