&par Example Description

This example describes how to use the USB OTG device module on APM32F107 to
enumerated as a MSC USB disk. This example use PC as host, and APM32F107 will
use sram array to simulate a fake U disk, unable to store files, only Used to
test speed of file transfering.

The UART4 is configured as follows:
  - TX:PC10, RX:PC11
  - BaudRate = 115200 baud
  - Word Length = 8 Bits
  - One Stop Bit
  - No parity
  - Hardware flow control disabled (RTS and CTS signals)
  - Receive and transmit enabled
