As a USB device may be hot-plugged, it is essential to have the configurable delays between power switching and device attachment, and when the device's internal power has stabilized.

* After a port is reset or resumed, the USB System Software is expected to provide a “recovery” interval of 10 ms before the device attached to the port is expected to respond to data transfers. * After a port is reset or resumed, the USB system software is expected to provide a "recovery" interval of 10 ms before the device attached to the port is expected to respond to data transfers.
* After the reset/resume recovery interval, if a device receives a SetAddress() request, the device must be able to complete processing of the request and be able to successfully complete the Status stage of the request within 50 ms. * After the reset/resume recovery interval, if a device receives a ``SetAddress()`` request, the device must be able to complete processing of the request and be able to successfully complete the Status stage of the request within 50 ms.
