Thanks Derrel,
I red a lot of posts as indicated.
I am asking if there is a "final summary "available in which the final hardware and software configuration is described.
In my personal case I shall use the 18f4455 device and the crystal oscillator that could be 20 Mhz or 4 MHz. No bus power will be used.
What will be the configuration set up ? ( include, define ... etc )
What is the program to callup every cycle in my PBP program to comunicate and to receive USB data?
I am sorry but reading all the above posts I still not have a clear understanding.
Thanks for any help.
Best regards,
Ambrogio
