I am a new kinetis user. I was wondering if there is a detailed hardware description of the USB peripheral used in Kinetis processors. I got the USB OTG/Host/Device stack user manual and the reference manual of the processor (K60) that I am using. However, I believe it does not cover all the details. There are lot more things done in USB_LDD code, than what is given in the reference manual. Any pointers would be of great help.
