IStiDeviceControl::GetMyDeviceOpenMode
Allows a still image minidriver to obtain the transfer mode that an application specified when it created an instance of a still image device.

IStiDeviceControl::GetMyDevicePortName
Allows a still image minidriver to obtain a device's port name.

IStiDeviceControl::Release
Closes an instance COM object that defines the IStiDeviceControl interface, and removes access to the interface.

IStiDeviceControl::WriteToErrorLog
