Hi

  I want to reset USB device,  host driver calls the WDF interface funcion:
```WdfUsbTargetDeviceResetPortSynchronously , It will reset the usb device and  enumerate again.

 But it takes long time to reset USB device, about 30 seconds.  add stop and start all pipes the  cost time no changed.

 But if reset device by reset hardware button on board, it will reset and enumerate at once.

How can i reset USB device just like reset hardware button?  no more than 2 seconds.

Thank you!
