Hi All Members
Unfortunately working on my usb project stopped sometimes
I started it 3 days ago!
Here is current status:
1- Receive 64 byte device descriptor request
2- Send first 16 of bytes device descriptor
3- Receive set address request
4- set address command/set endpoint enable command/send zlp
5- Receive 18 byte device descriptor request
6- Send first 16 bytes of device descriptor
7- Send second 2 bytes of device descriptor

But it seems there is not any effect after step 6
and after 3 bus reset system goes to suspend state

I must appreciate from all who help me on this thread Specially Tsuneo because of his informative and purely helps
