Hello,

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.

What's wrong???

Hi Martin,

K70 has two different USB ports:

High-speed USB port can be accessed using TWR-SER2 board because you need the external USB HS PHY

Full-Speed USB port can be accessed using TWR-SER board

Are u opening the correct project for the USB module that you want?

also inside the documentation folder there is a file called USBHWCONFIG.pdf that shows the correct jumpers configuration for each board and use case.

Let me know if you still have problems and I will post more information.

regards
