Abstract

To provide a USB communication device that functions as a USB host while being capable of performing data communication during power supply.SOLUTION: A host wireless adapter 93 includes an optical LAN-USB protocol conversion unit 94 and a wireless USB host 95. A plug 60 is connected to the host wireless adapter 93, and a power line 88 and a ground line 89 are connected to a power supply unit to drive the optical LAN-USB protocol conversion unit 94 and the wireless USB host. An optical fiber 20' is connected to the optical LAN-USB protocol conversion unit. The optical LAN-USB protocol conversion unit converts a LAN signal, which is transmitted via the optical fiber 20' from a HUB of a distribution board through an outlet, according to the USB protocol and outputs the converted signal to the wireless USB host. The wireless USB host transmits the USB signal as radio waves from an antenna 96.SELECTED DRAWING: Figure 11
