STM32F407 USB Changing Endpoint

Question asked by himan on Sep 1, 2012

i currently try to change the endpoint of a demo application from e.g. EP1 to EP2. After changing there is no communication anymore. While debugging i find out, that the fifo of EP2 was set to 0 (in the core configuration) that means no buffer free. I changed this to 128 and the data are copied to the fifo buffer but there is still no transaction. Does anybody konw which additional changes have to be done for a proper working of EP2 (or EP3) instead of EP1 ?

Best regards,
