This function is the HC driver MDD power-up handler.

);

Parameters

  • lpvOhcdObject
    [in] Pointer to a host controller interface driver object.

Remarks

This function should be called by the PDD as part of processing this function. It causes the MDD to restore state and reinitialize the host controller interface hardware. All client drivers loaded at the time that the power is turned off are unloaded. Once this is completed, the host controller interface hardware is placed into the OPERATIONAL state, and drivers for devices that are still attached to the USB are loaded.

Requirements

OS Versions: Windows CE 1.0 and later.
Header: Ohcdddsi.h or Uhcdddsi.h.
