title: Accessing USB port programmatically
body: <p>I was doing some work on MSP430 series MCU.<br>
  I have designed a GUI (using wxPython). Now I want to control microcontroller with GUI, but I can't find any modules in python that can send data to the USB port so that the microcontroller can identify it. </p>
  
  <p>Does there exist any module that can send and receive data to/from  USB port?</p>
  
  <p>Thanks in advance. </p>
