Abstract
A recording apparatus can shift to power saving modes even when the recording apparatus is connected to the host PC, thus reducing power consumption. The recording apparatus can switch to a first power saving mode to supply power that enables detection of an inquiry from a host device and also switch to a second power saving mode to supply power that enables responding to an inquiry from the host device about information as to the memory card. Prior to switching to the first power saving mode, the recording apparatus stores information about a memory card attached to the card slot in a memory unit. In response to detection of an inquiry from the host device, the recording apparatus switches from the first power saving mode to the second power saving mode, and notifies information stored in the memory card controller to the host device.
