Hey guys

I'm working on a projet and i'm using STM32f4 discovery board.
I wrote program to send data by USB (from MCU to PC by Bulk transfert) in full speed mode.
Usually the throughput should be 12 Mbits/s but mine is only 5.6 Mbits/s.
Send process looks like that :

while(1){
     SendData(...)
}

 If you have any idea why and how I can increase it ??


Thank by advance
