Method for a 4-port USB connector with an integrated USB hub

Disclosed is a method for a 4-port USB connector with an integrated USB hub. Benefits include improved functionality and improved design flexibility.

Background

        � � � � � Routing a single 4-port USB connector jack to the rear I/O panel on a motherboard is very difficult. As a result, conventional designs typically use dual-port connector jacks. In some situations, the difficulty in routing prohibits routing more than one USB dual-port connector jack to the rear I/O panel. The board space is insufficient for a USB hub chip plus the required passive components on the motherboard near the rear I/O panel. As a result, supporting four USB ports in the rear I/O panel area requires sacrificing valuable routing area on the motherboard.

Description

        � � � � � The disclosed method integrates a 4-port USB hub controller into the USB connector stack typically used in a desktop motherboard (see Figure 1).

        � � � � � The key elements of the method include:

•        � � � � USB connector with four jacks

•        � � � � 4-Port USB hub controller integrated into the USB connector

•        � � � � Separate power and status light-emitting diodes per port

        � � � � � The disclosed method resolves the problem of having 4 USB ports in a single connector stack in the rear I/O panel. This solution requires a single USB data pair (D+/D-) routed from the USB host controller to the rear I/O panel.

        � � � � � All the required components and the USB hub physical...
