   @acassis you need an app sending (keep the channel busy)/rxing data to/from PC.
   
    1) Detect the VBUS (GPIO) off. 
   2) Kill the app
   3) serdis
   4) Wait for VBUS ON. (GPIO) 
   5) sercon. 
   6) launch the app. 
   
   The app will be blocked* after the TX buffer fills and the 4 req are left waiting on the EP IN Int.
   
   *If the connection is broken while the active is set it
