MK22FN256VLH12 USB

Hello, I'm using the MK22 USB to be a HID generic device( to output huge ADC datas to PC) , I find the demo code is running at its KHCI mode in the Demo code, I search the KHCI in internet but fail to find much message about KHCI, could you just tell me the different between KHCI and EHCI ? 

if I want to run the device on its high speed(480Mbps) , I just set the macro USB_DEVICE_CONFIG_EHCI to 1U and set the USB_DEVICE_CONFIG_KHCI to 0U, am I right ?

if I want to run the device on its full speed(12Mbps), the demo code would be OK?

thanks
