Dear Tsuneo
I am sure i send all parts of device descriptor to the host
but not on it's method
i call read buffer after each write buffer and show it in main
The main routine shows that all parts all are send
But i am sure the method is not true
I use NUMBER_OF_FRAME as a counter for sending each part
After any control in interrupt i send one part but there isn't any more control in interrupt and a bus reset occurs
After that an extera control in interrupt occurs and the counter increased by 1, so i send second part of device descriptor and i can see read buffer data is equal with write buffer data

Thanks for your time
