Linux Api CyOpen not working under CDC Mode for CY7C65211

Hi all,

I've install the SO library into my raspberry pi and device able to detect after i plug it in to usb port. However when i try to turn on one of the GPIO pin, my C code at CyOpen step return CY_ERROR_DRIVER_OPEN_FAILED status. I checked my device with config tool in window and found out the CY7C65211 is using CDC mode. If i change it to VENDOR then my C code runs fine without error.

So the question is, CY7C65211 CyOpen will fail if it is using CDC mode in linux? I tried my program on window CyOpen works for both CDC and VENDOR mode. Please advice how do i make this work in linux.

Thanks.

Regards.
