comments

The USBSerial constructor waits until the device is connected. So if the cable is not plugged, the mbed will hang. 
You can see if the connection is working in the device manager on windows. 
I think that the best way to check the usb connection is USBMouse. 
If the cursor is moving on your screen, it means that the usb connection is correct.
