Hi all,

I'm using FRDM-K22F board for a USB device application using KDS SDK.
I started from MSC sample to have bulk in/out.

All working fine except it is USB Full Speed.

I want to enable my device as HIGH_SPEED, I need to rebuild usbd_sdk_frdmk22f120m_mqx which needs EHCI as host controller interface.

The problem is, I cannot find the ehci interface source code anywhere in my KDSK while I have all concerning KHCI in "MQX_KSDK_1.0.0\usb\usb_core\device\sources\controller"

Am I missing something?

How to enable HIGH Speed config on K22F using KDS.

Thanks for your help.
