I have 2 questions rearding the Kinetis-L (Specifically the KL25).


1) I have seen multiple examples of the a USB composite devices on the Kinetis-K series, but have not seen any examples of a composite device on the Kinetis-L series.  Specifically, in the USB Stack v5.0 There is a bullet stating that there is a HW endpoint number limitation which causes the msd_cdc example to not work with the HS USB controller.   Also, Table 6.1 regarding Composite Mode Demo’s not being available for the FRDM-KL25 seems to indicate there is no support:




Are there any examples of a USB Composite Device for any of the Kinetis L Series?  Is there some hardware limitiation that prevents composite operation on a KL?


Specifically we are looking to support.  Specifically we need supoport HID (Mouse) and CDC classes.
