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

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,

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);
    }
