Patent ID: 8244940

Claim:
A peripheral device for performing data communication with a host device via one of a first-type interface and a second-type interface having different data-communication-related specifications, comprising: a single connector that is to be connected selectively with one of a first-type connector corresponding to the first-type interface and a second-type connector corresponding to the second-type interface; and a controller for performing an initial connection process that is started by a signal sent from the host device when the peripheral device and the host device are physically connected with each other by using one of the first-type connector and the second-type connector, and that makes a logical connection between the peripheral device and the host device via one of the first-type interface and the second-type interface, wherein the second-type connector includes terminals using data communication via the second-type interface in addition to terminals using data communication via the first-type interface, wherein at least part of the terminals using data communication via the second-type interface are located in a deeper position as compared with the terminals using data communication via the first-type interface, and wherein the controller can perform a reconnection process that breaks the logical connection made by the initial connection process and then makes the logical connection between the peripheral device and the host device, while the physical connection is maintained.
