I installed Freescale USB stack v4.0.2 and Codewarrior 10.3. I opened HID device sample project for K70 - Freescale USB Stack v4.0.2\Source\Device\app\hid\cw10\kinetis_k70 and downloaded it to my TWR-K70 via its integrated OSJTAG. Then connected second USB cable to micro connector of TWR-SER.
I get a message with yellow exclamation mark, that Win8 can't recognize USB device.
I get the same message when I run MSD sample project.
