I assume you're talking about connecting CYUSB3014 without any firmware loaded. Please confirm.
Anyways VID/PID 0000/0000 means that the host is not able to talk to the device. It knows there is a device connected but the device isn't responding to any of its requests.
If a firmware is not loaded, then you would want to review your schematic and layout using AN70707 - EZ-USB® FX3 Hardware Design Guidelines and Schematic Checklist as reference.
If firmware is loaded, it could be firmware issue too. In that case, Please disable bootloading to isolate whether it is a firmware issue or hardware issue.
