摘要

A method to enable a vehicle's embedded USB Host system to connect to multiple mobile devices through a USB Hub, regardless of whether the mobile devices are configured to act as USB Hosts or USB Devices, without USB On the Go (OTG) controllers or additional vehicle wiring, or inhibiting the functionality of any consumer devices connected to the same USB Hub. Preferably, the method is configured to provide that no additional cabling is required, and no hardware changes are required to be made to the HU. The method can be employed between a vehicle's embedded USB Host, USB Hub and at least one consumer accessible USB port. When the consumer device is acting as a USB Host, signals between the consumer device and the vehicle's embedded USB Host are processed through a USB bridge, thereby rendering the consumer device compatible with the vehicle's embedded USB Host.

RELATED APPLICATIONS

This application is a continuation application and claims benefit under 35 U.S.C. § 120 of U.S. patent application Ser. No. 15/441,775, filed Feb. 24, 2017, which claimed benefit of U.S. patent application Ser. No. 15/268,728, now U.S. Pat. No. 9,619,420, filed Sep. 19, 2016, which claimed benefit under 35 U.S.C. § 120 of U.S. patent application Ser. No. 14/487,947, now U.S. Pat. No. 9,460,037, filed on Sep. 16, 2014, which claimed benefit under 35 U.S.C. § 119(e) of U.S. Provisional Patent Application No. 61/882,915, filed on Sep. 26, 2013, the entire disclosure of each of which are hereby incorporated herein by reference.

BACKGROUND

The present invention generally relates to Universal Serial Bus (“USB”) connectivity between, for example, mobile consumer devices and vehicle electronic systems. More specifically, the present invention relates to a system which is configured to provide that consumer devices that act as either USB host or USB device can connect to a vehicle's embedded USB host that does not have On the Go (“OTG”) capability through an embedded USB hub in the vehicle.

What is claimed is:1. A method, comprising:providing efficient communications among USB components of a data communication system that includes a first input port, a second input port, a USB hub, a USB bridge connected to the USB hub, an embedded USB host connected to the USB hub, a USB port connected to a USB device capable of operating in a USB Host mode and a USB device mode, and USB multiplexing switches connected to the USB port, the USB hub, and the USB bridge;receiving a first USB signal from the USB device via the USB port while the USB device is operating in the USB host mode;routing the first USB signal via the USB multiplexing switches from the USB device to the embedded USB host through the USB bridge and the USB hub;receiving a second USB signal from the USB device via the USB port while the USB device is operating in the USB device mode; androuting the second USB signal via the USB multiplexing switches from the USB device to the embedded USB host through the USB hub, wherein the second USB signal from the USB device to the embedded USB host bypasses the USB bridge.
