UhciDriverBindingStart()

EFI_STATUS EFIAPI UhciDriverBindingStart	(	IN EFI_DRIVER_BINDING_PROTOCOL *	This,
		IN EFI_HANDLE	Controller,
		IN EFI_DEVICE_PATH_PROTOCOL *	RemainingDevicePath
	)

Starting the Usb UHCI Driver.

Parameters

This	Protocol instance pointer.
Controller	Handle of device to test.
RemainingDevicePath	Not used.

Return values

EFI_SUCCESS	This driver supports this device.
EFI_UNSUPPORTED	This driver does not support this device.
EFI_DEVICE_ERROR	This driver cannot be started due to device Error. EFI_OUT_OF_RESOURCES- Failed due to resource shortage.

Definition at line 1609 of file Uhci.c.

UhciDriverBindingStop()

EFI_STATUS EFIAPI UhciDriverBindingStop	(	IN EFI_DRIVER_BINDING_PROTOCOL *	This,
		IN EFI_HANDLE	Controller,
		IN UINTN	NumberOfChildren,
		IN EFI_HANDLE *	ChildHandleBuffer
	)

Stop this driver on ControllerHandle. Support stopping any child handles created by this driver.

Parameters

This	Protocol instance pointer.
Controller	Handle of device to stop driver on.
NumberOfChildren	Number of Children in the ChildHandleBuffer.
ChildHandleBuffer	List of handles for the children we need to stop.

Returns

EFI_SUCCESS
