Hi,

There is an USB_device project example for K40 development kit, which is included in the KINETIS512_SC folder

 

Has anybody tried and used the the example successfully? 

I can't get it to work since the enumeration process doesn't get finished and eventually issues the message "USB Device Not Recognized"

Thank you for any help you can provide.
