Abstract
A wireless hub, connected to the USB bus of a computer, and a wireless port, connected to a USB interface of a peripheral device, are provided, and wireless communication is performed between the two. The wireless hub performs communication with the computer by converting a USB packet routed to a device into a wireless signal, and a wireless signal received from a device into a USB packet. The wireless port attached to each device also converts a wireless signal into a USB packet and vice versa. While it is normal for a plurality of wireless ports to be connected to a single wireless hub, an arrangement of one wireless hub and a corresponding single wireless port is also possible. A wireless hub and a wireless port each have a device identifier assigned to them, and in the USB-wireless conversion, a non-specific destination identified by a USB address and bus topology is converted into a device identifier. Inter-host communication is enabled by using the device identifier.
