ABSTRACT:
A host apparatus that adjusts consumption of a device in accordance with the power supply capability of the host apparatus. The host apparatus includes a plurality of communication ports and devices connected to each communication port. A host controller of the host apparatus communicates with the devices to acquire equipment information including the consumption current of each device. A current supply circuit supplies current to the devices connected to the communication ports. An MPU changes the current supplied from the current supply circuit to the plurality of devices when a total value of the consumption current of a device newly connected to the plurality of communication ports and the consumption current of each device for which connection with the plurality of ports has already been recognized exceeds the current that the current supply circuit is capable of supplying.
