// (1)Usb controller(s) (2)Usb port(s) (3)Usb device(s) you want to ignore
//
// 1. To ignore Usb controller : Insert a PCI_DEVICE_PATH to UsbIgnoreDevicesPtr
// and set appropriate value into "Function" and "Device" fields
//
// 2. To ignore Usb port : Insert a USB_DEVICE_PATH to UsbIgnoreDevicesPtr
// and set appropriate value into ParentPortNumber
//
// 3. To ignore Usb device : Insert a USB_CLASS_DEVICE_PATH to UsbIgnoreDevicesPtr
// and set appropriate value into "VendorId" and "ProductId" field
//
// 4. Every device path MUST end as a END_DEVICE_PATH in order to distinguish each other
//
// 5. Append 0(UINT32) after end of whole device paths to indicate the end of whole device paths
//
// Turn following code on to enable this feature
