I don't know. Fundamentally, PIC doesn't start when Atmega is connected to it. At the moment I don't know why.
Before trying another PIC firmware, try to pull pin 26 of PIC18F2550 to +5 (Vcc) over a 10k-47k resistor as suggested in viewtopic.php?f=3&t=268

No nothing !Anyway!i will try tommorow with the new firmware...!Thank you for now see you tommorow!

Don't forget, with my USB PIC firmware you need to pull pin 26 of the Pic to ground over a 22k-47k resistor.

Read 'Related Software' subforum and if you have questions, raise them there.

why could the synthex firmware did not work?

Strange.
With my PCBs, it's always work.
I will investigate the matter.
