Client drivers must not use WDM power IRPs to selectively suspend their devices.
The Windows selective suspend behavior is different for devices operating in Windows XP and Windows Vista and later versions of Windows. DMA transfers by the host controller to the scheduler can prevent the system's processors from entering deeper sleep states, such as C3. More importantly, any device that is not selectively suspended may prevent the USB host controller from disabling its transfer schedule, which resides in system memory. Suspending such devices, when the device is not in use, reduces overall power consumption. Many devices, such as fingerprint readers and other kinds of biometric scanners, only require power intermittently. Selective suspension of USB devices is especially useful in portable computers, since it helps conserve battery power. The USB selective suspend feature allows the hub driver to suspend an individual port without affecting the operation of the other ports on the hub.

In Microsoft Windows XP and later operating systems, the USB core stack supports a modified version of the 'selective suspend' feature that is described in revision 2.0 of the Universal Serial Bus Specification. This section provides information about choosing the correct mechanism for the selective suspend feature.
