CDC on K60

Question asked by Michael McCarrick on Oct 8, 2014

I am using the Freescale USB Stack version 4.1.1 in a K60 based system.  The CDC code is operating as long as the USB cable is not connected when the system is started.  If I start the system then connect the USB cable I can open the associated COM port and communicate.  If the cable is connected when the system first starts or after a reset I am not able to connect (open the associated COM) port.  I must unplug and replug the USB cable while the K60 is running before I can open the associated COM port.


Any suggestions on how I can get this to work such that the USB cable can be connected while the K60 is powered up?
