Hello all,

I am using STM32F407 , in that i am able to communicate with USB Full speed mode. In that i am trying to send data serially from android phone which act as a Host and STM32F407 act as Device. When i trying to send 2KB data serially to my USB device. I am not able to receive the complete data and only 255 bytes are received in terms of 64 bytes chunks. How to receive 2KB data in a single transmission. What are all changes needed to be done to receive the large datas?
