title: What is the maximum speed of the STM32 USB CDC?
body: <p>I'm using an STM32L151 to communicate with a PC using USB CDC. I used the STM32 HAL libraries to create my project.
  I found that the USB sends data in 1 ms intervals, and each time 64 bytes are being sent. So, is the maximum speed of the USB CDC 64 kbyte/s? That is much lower than the USB Full Speed data rate of 12 Mbit/s. How can I reach this speed, or at least a fraction of this speed?</p>
