Hello
 
I'm working on using USB using the MCF52223 for one of my projects.
I've manage to detect Host and slave connection and disconnection.
When the PC is connected:
I Wait for a reset then when i get it
- i set EP0 in default state
- Send a reset for 10ms
-  switch on the USB_EN_SOF_EN bit
- Get EP0 ready for reception (packet size 8 byte, OWN, DTS)
and expect to get an TOK_DNE interrupt
But it dowsn't happens....
 
Please Help
 
thanks loads
Olivier
