&par Example Description

This example describes how to use OTG to simulate a HID mouse.
When PC enter sleep mode, device will enter lowpower mode.
You can wake up the PC and the device at the same time by using
another keyboard and mouse device on the PC or by pressing the KEY1.

Press KEY2 will move the cursor to the right.

&par Hardware Description

The USART1 is configured as follows:
    - TX:PA9, RX:PA10
    - BaudRate = 115200 baud
    - Word Length = 8 Bits
    - One Stop Bit
    - No parity
    - Hardware flow control disabled (RTS and CTS signals)
    - Receive and transmit enabled

    - OTG_FS_VBUS(PA9) ----------> X(Use to USART1)
    - OTG_FS_ID(PA10)  ----------> X(Use to USART1)
    - VCC5V            ----------> VBUS
    - OTG_FS_DM(PA11)  ----------> USB_DN
    - OTG_FS_DP(PA12)  ----------> USB_DP
    - GND              ----------> GND
