Usb 2.0 device enumeration using UCX framework

Hi, We are developing Host Controller driver using UCX extension(WDK version 1709). We have successfully enumerated usb 3.0 device, but when we try to enumerate 2.0 device, we are having issues with port reset. When we signal port change on root hub, enumeration starts, UCX framework calls SetPortFeature(PORT_RESET) four times and then finishes(in USBView this is shown as PORT RESET FAILED). There are no GetPortStatus calls between, where we can signal that reset has completed. How can we signal to UCX that reset has been finished on device during SetPortFeature(PORT_RESET) calls?
