Hi,

I'd highly recommend you to choose the USB demos which is from the Kinetis SDK, and the most updated USB stack also integrates into the Kinetis SDK.

Regrading to the USB stack 4.1.1, the updates have been halted, as it has none of teams to cover it now.

Please refer to the thread below to install the Kinetis SDK 2.0

How to: install KSDK 2.0
Have a great day,
