 		 #107632 - I don't know why d12 don't interrupted
Responding to: ???'s previous message

Nonetheless, bear in mind that I am going only on what I am able to glean from the documents. I could very well be wrong. That is something you will have to determine by trial and error.
I really do want to know if this works. And if not what does?

Saalam,
Before sending this http://www.8052.com/forum/read.phtml?id=107605 i had tried your approach
I wrote 16 bytes of device descriptor to ep0in at first
then i call d12init and i read ep0out endpoint buffer
the result was the same 80H 06H 00H 01H 00H 00H 40H 00H
I don't know why d12 don't interrupted mcu at epoin?
