title: STM32F411 I need to send a lot of data by USB with high speed
body: <p>I'm using STM32F411 with USB CDC library, and max speed for this library is ~1Mb/s.
  I'm creating a project where I have 8 microphones connected into ADC line (this part works fine), I need a 16-bit signal, so I'm increasing accuracy by adding first 16 signals from one line (ADC gives only 12-bits signal). In my project, I need 96k 16-bit samples for one line, so it's 0,768M signals for all 8 lines. This signal needs 12000Kb space, but STM32 have only 128Kb SRAM, so I decided to send about 120 with 100Kb data in one second.</p>
  
  <p>The conclusion is I need ~11,72Mb/s to send this.</p>
  
  <p>The problem is that I'm unable to do that because CDC USB limited me to ~1Mb/s.</p>
  
  <p>Question is how to increase USB speed to 12Mb/s for STM32F4. I need some prompt or library.</p>
  
  <p>Or maybe should I set up "audio device" in CubeMX?</p>
