Abstract
A connection device for connecting between a multifunction peripheral and USB devices. A hub unit is disconnectably connected to the multifunction peripheral via a first interface for enabling power supply from the multifunction peripheral to the hub unit. The hub unit is also disconnectably connected to the USB devices via a second interface for enabling power supply from the hub unit to the USB devices. A dedicated power supply connector is connected to a power supply section of the multifunction peripheral via wiring for enabling power supply from the multifunction peripheral to the hub unit. A hub circuit relays data between the multifunction peripheral and one of the USB host connectors of the hub unit. Power from the first interface to the hub circuit is supplied through a first power path, and power from the multifunction peripheral to the USB devices is supplied through a second power path.
