Abstract:
A control unit of a USB 3.0 device controls the USB 3.0 device that has entered an SS.Disabled state to transition to an Rx.Detect state when a USB 2.0 connection is not established after a predetermined time, in which the USB 2.0 connection is one of an HS (High Speed) connection, an FS (Full Speed) connection, and an LS (Low Speed) connection. This enables quick return to the Rx.Detect state for the USB 3.0 device that entered the SS.Disabled state due to an error in the host.
