This method is called to enforce an an idle policy for the device. Note, the idle policy is only active while the interface is open and is reset when closed. Availability: This function is only available with IOUSBInterfaceInterface800 and above.
Parameter self: Pointer to the IOUSBInterfaceInterface.
Parameter deviceIdleTimeout: The amount of time in ms a device is idle before it can be suspended. Use 0 to prevent suspending an idle device.
Returns: Returns kIOReturnSuccess if successful, kIOReturnNoDevice if there is no connection to an IOService, kIOReturnUnsupported is the bus doesn’t support this function.
SetPipeIdlePolicy: Option<unsafe extern "C-unwind" fn(*mut c_void, u8, u32) -> i32>Define an idling policy for the interface.
This method is called to enforce an an idle policy for the pipes. Note, the idle policy is only active while the interface is open and is reset when closed. Availability: This function is only available with IOUSBInterfaceInterface800 and above.
Parameter self: Pointer to the IOUSBInterfaceInterface.
Parameter pipeRef: Index for the desired pipe (1 - GetNumEndpoints).
Parameter ioIdleTimeout: The amount of time in ms an IO is pending before it allows the device to be considered idle. Use 0 to prevent idling the device while the IO is in progress, regardless of how long it takes.
Returns: Returns kIOReturnSuccess if successful, kIOReturnNoDevice if there is no connection to an IOService, kIOReturnUnsupported is the bus doesn’t support this function.
