This is because the STM32F3Discovery board does not provide circuitry for
control of the "soft connect" USB pullup. As a result, the host PC
does not know the USB has been logically connected or disconnected. You
have to follow these steps to use USB:
1) Start NSH with USB disconnected
2) enter to 'sercon' command to start the CDC/ACM device, then
3) Connect the USB device to the host.
