Hi,

How can I make CyUSB3014 switch from a usb3.0 device to a usb2.0 device?

Intel chipset if you connect a USB2.0 device and USB3.0 device will used different usb port.

Regards,

Ethan

Please use the code below in Init function.

    /* Connect the USB Pins with super speed operation enabled. */

    apiRetStatus = CyU3PConnectState(CyTrue, CyFalse);

    if (apiRetStatus != CY_U3P_SUCCESS)

    {

        CyU3PDebugPrint (4, "USB Connect failed, Error code = %d\n", apiRetStatus);

        CyFxAppErrorHandler(apiRetStatus);

    }

Hello Ethan,

The CYUSB3014 USB3.0 PHY can be disabled and made to operate in USB2.0 by setting the ssEnable parameter of the CyU3PConnectState() API to CyFalse.

Best regards,
