I am trying to add USB virtual com port to a custom board using the MK66FX controller. I have searched the forum and internet, but have not succeeded in finding any good instructions on how to do this. There are a lot of information about usb on Kinetic, but most seems to be for evaluation boards or older versions of the SDK no longer supported.


I am using:




MQX Standard


For the moment my project contains the following USB related components:


This compiles and runs, but not surprisingly nothing exciting happening.

There is obviously missing a lot to complete the CDC virtual com function, but I am a little stuck and hope that someone can point me in the right direction to go from here, or maybe I have already started out the wrong way?
