hello, i built the t.h. version. All work fine until I plug any microcontroler to the usbpicprog, then the program dont detect the pic, act like i dont plug the pic. I used 3 different pics. I use the hardware test (Test I/o) and on VPP in 5v i get around 4,32V, and with 12v i get 0V.
the other pins are OK. I didnt put the 12V zener called D8 because the schematic show as NA. What i need to check or make to solve the problem. thanks
