For built-in miniport drivers, the system calls the miniport driver's reset handler function upon a Power-Up event. The miniport reset handler should issue a hardware reset to the peripheral and reset the driver's software state.

If more explicit power handling is required (for example, to power off the peripheral from the miniport), the miniport could register itself as a Stream Interface driver and receive notifications on Power-Down and Power-Up system events. This option should only be required if the platform does not perform the necessary power handling of the peripheral in the OAL. Also, miniport drivers that register as Stream Interface drivers should call only raw I/O functions in the power handler. For more information on restrictions in power handling for Stream Interface drivers, refer to the Windows CE Device Driver Kit.
