Hi,
Please refer the link http://msdn.microsoft.com/en-us/library/windows/hardware/ff537056(v=vs.85).aspx to know about the URBs.
If the uRB is related to OUT endpoint then in the device there should be an OUT endpoint and the fimrware inside the CY7C64713 should have enabled the endpoint and it can commit the data to peripheral domain, it can edit ok it can skip the data.
For more details about the firmware handling refer the technical reference manual
Regards,
VIkas.
