This function is the power handler for the USB host controller driver model device driver (MDD).

Syntax

void HcdPdd_PowerUp(
  DWORD dwDeviceContext 
);

Parameters

  • dwDeviceContext
    [in] Pointer to the device context returned from the HcdPdd_Init function.

Return Value

None.

Remarks

This function executes when the system boots. This function must call the HcdMdd_PowerUp function to enable the model device driver (MDD) to restore state information. The host controller interface (HCI) memory area, as passed to the HcdMdd_CreateHcdObject function, must be preserved across a power cycle. No system calls can be made from within this function.

Requirements
