Anytime I call "CyU3PUsbGetDevProperty(CY_U3P_USB_PROP_FRAMECNT,&Frame);" I get "CY_U3P_ERROR_BAD_ARGUMENT" returned. I am succesfully firing a USB event callback on each SOF and I then need to detect the '0' frames whilst still in the event callback. I am using 1.2.3 libraries. How do I make this work?

Hi,
You can get the framecount value only if your device connection is in USB 2.0 mode.
Based on the output that you are seeing, I am assuming that your device connection is in SuperSpeed.
Please confirm this.
Thanks,
Sai Krishna.
