Hi Tom!
I've finally programmed the atmega and the Pic.
But the USB connection doesn't work at all with my pc.
I tried 2 different cables and the power sources...but nothing...
The USB led is always off but the status and pwr led are on.
I made 2 PCB and both have the same problem...
Do you have any suggestions?
