FRDM-K28F USB configuration.

I have a FRDM-K28F board and need to use the USB port, but regardless of which project example I create using the MCUXpresso  I can not make the USB port "alive" for Windows to see. When I do the same with my FRDM-K64F board there are no problems, all is working. I fear I do not understand what jumper setting I should apply on my FRDM-K28F as I just got it a few days ago, or perhaps my board is broken somehow.

 

The User's guide for the FRDM-K28F is not much help, e.g. it doen't even show where the jumpers are placed on the board, do anyone have a better description on how to setup the board so the USB port attached to the K28 processor is working, or perhaps even a project including source code that is guaranteed to work?

 

My USB SDA port seems to work fine, I am using the IAR Workbench for development and I can compile, download and execute programs just fine.
